An original watercolour illustration for the cover of Harry Potter and the Philosopher’s Stone, 1997 — the first book in J.K. Rowling’s hit series—could sell for US$600,000 at a Sotheby’s auction this summer.
The illustration is headlining a June 26 sale in New York that will also feature big-ticket items from the collection of the late Dr. Rodney P. Swantko, a surgeon and collector from Indiana, including manuscripts by poet Edgar Allan Poe and Arthur Conan Doyle, author of the Sherlock Holmes books
The Harry Potter illustration, which introduced the young wizard character to the world, is expected to sell for between US$400,000 to US$600,000, which would make it the highest-priced item ever sold related to the Harry Potter world. This is the second time the illustration has been sold, however—it was on the auction block at Sotheby’s in London in 2001, where it achieved £85,750 (US$107,316).
The artist of the illustration, Thomas Taylor, was 23 years old at the time and a graduate student working at a children’s bookshop. According to Sotheby’s, Taylor took a “professional commission from an unknown author to visualise a unique wizarding world,” Sotheby’s said in a news release. He depicted Harry Potter boarding the train to Hogwarts on platform9 ¾ platform, and the illustration became the “universal image” of the Harry Potter series, Sotheby’s said.
“It is exciting to see the painting that marks the very start of my career, decades later and as bright as ever! It takes me back to the experience of reading Harry Potter for the first time—one of the first people in the world to do so—and the process of creating what is now an iconic image,” Taylor said in the release.
Meanwhile, to commemorate the 175th anniversary of Edgar Allan Poe’s For Annie , 1849, Sotheby’s recently reunited the autographed manuscript of the poem with the author’s home, Poe Cottage, in the Bronx.
The cottage is where the author lived with his wife, Virginia, and mother-in-law, Maria Clemm, from 1846 until he died in 1849. The manuscript, also from the Swantko collection, will remain at the home until it is offered at auction at Sotheby’s on June 26 with an estimate between US$400,000 and US$600,000.

Poe Cottage, preserved and overseen by the Bronx County Historical Society, is home to many of the author’s famous works, including Eureka , 1948, and Annabel Lee , 1927.
“To reunite the For Annie manuscript with the Poe Cottage nearly two centuries after it was first composed brought to life literary history for a truly special and unique occasion,” Richard Austin , Sotheby’s Global Head of Books & Manuscripts, said in a news release.
For Annie was one of Poe’s most important compositions, and was addressed to Nancy “Annie” L. Richmond, one of the several women Poe pursued after his wife Viriginia’s death from tuberculosis in 1847.
In a letter to Richmond herself, Poe proclaimed For Annie was his best work: “I think the lines For Annie much the best I have ever written.”
The poem was composed in 1849, only months before Poe’s death, Sotheby’s said in the piece, Poe highlights the romantic comfort he feels from a woman named Annie while simultaneously grappling with the darkness of death, with lines like “And the fever called ‘living’ is conquered at last.”

In the margins of the manuscript are the original handwritten instructions by Nathaniel P. Willis, co-editor of the New York Home Journal, where Poe published other poems such as The Raven and submitted For Annie on April 20, 1849.
Willis added Poe’s name in the top right and instructions about printing and presenting the poem on the side. The poem was also published in the Boston Weekly that same month.
Another piece of literary history included in the Swantko sale could surpass US$1 million. Conan Doyle’s autographed manuscript of the Sherlock Holmes tale The Sign of Four , 1889, is estimated to achieve between US$800,000 and US$1.2 million.

Selloff in bitcoin and other digital tokens hits crypto-treasury companies.
The hottest crypto trade has turned cold. Some investors are saying “told you so,” while others are doubling down.
It was the move to make for much of the year: Sell shares or borrow money, then plough the cash into bitcoin, ether and other cryptocurrencies. Investors bid up shares of these “crypto-treasury” companies, seeing them as a way to turbocharge wagers on the volatile crypto market.
Michael Saylor pioneered the move in 2020 when he transformed a tiny software company, then called MicroStrategy , into a bitcoin whale now known as Strategy. But with bitcoin and ether prices now tumbling, so are shares in Strategy and its copycats. Strategy was worth around $128 billion at its peak in July; it is now worth about $70 billion.
The selloff is hitting big-name investors, including Peter Thiel, the famed venture capitalist who has backed multiple crypto-treasury companies, as well as individuals who followed evangelists into these stocks.
Saylor, for his part, has remained characteristically bullish, taking to social media to declare that bitcoin is on sale. Sceptics have been anticipating the pullback, given that crypto treasuries often trade at a premium to the underlying value of the tokens they hold.
“The whole concept makes no sense to me. You are just paying $2 for a one-dollar bill,” said Brent Donnelly, president of Spectra Markets. “Eventually those premiums will compress.”
When they first appeared, crypto-treasury companies also gave institutional investors who previously couldn’t easily access crypto a way to invest. Crypto exchange-traded funds that became available over the past two years now offer the same solution.
BitMine Immersion Technologies , a big ether-treasury company backed by Thiel and run by veteran Wall Street strategist Tom Lee , is down more than 30% over the past month.
ETHZilla , which transformed itself from a biotech company to an ether treasury and counts Thiel as an investor, is down 23% in a month.
Crypto prices rallied for much of the year, driven by the crypto-friendly Trump administration. The frenzy around crypto treasuries further boosted token prices. But the bullish run abruptly ended on Oct. 10, when President Trump’s surprise tariff announcement against China triggered a selloff.
A record-long government shutdown and uncertainty surrounding Federal Reserve monetary policy also have weighed on prices.
Bitcoin prices have fallen 15% in the past month. Strategy is off 26% over that same period, while Matthew Tuttle’s related ETF—MSTU—which aims for a return that is twice that of Strategy, has fallen 50%.
“Digital asset treasury companies are basically leveraged crypto assets, so when crypto falls, they will fall more,” Tuttle said. “Bitcoin has shown that it’s not going anywhere and that you get rewarded for buying the dips.”
At least one big-name investor is adjusting his portfolio after the tumble of these shares. Jim Chanos , who closed his hedge funds in 2023 but still trades his own money and advises clients, had been shorting Strategy and buying bitcoin, arguing that it made little sense for investors to pay up for Saylor’s company when they can buy bitcoin on their own. On Friday, he told clients it was time to unwind that trade.
Crypto-treasury stocks remain overpriced, he said in an interview on Sunday, partly because their shares retain a higher value than the crypto these companies hold, but the levels are no longer exorbitant. “The thesis has largely played out,” he wrote to clients.
Many of the companies that raised cash to buy cryptocurrencies are unlikely to face short-term crises as long as their crypto holdings retain value. Some have raised so much money that they are still sitting on a lot of cash they can use to buy crypto at lower prices or even acquire rivals.
But companies facing losses will find it challenging to sell new shares to buy more cryptocurrencies, analysts say, potentially putting pressure on crypto prices while raising questions about the business models of these companies.
“A lot of them are stuck,” said Matt Cole, the chief executive officer of Strive, a bitcoin-treasury company. Strive raised money earlier this year to buy bitcoin at an average price more than 10% above its current level.
Strive’s shares have tumbled 28% in the past month. He said Strive is well-positioned to “ride out the volatility” because it recently raised money with preferred shares instead of debt.
Cole Grinde, a 29-year-old investor in Seattle, purchased about $100,000 worth of BitMine at about $45 a share when it started stockpiling ether earlier this year. He has lost about $10,000 on the investment so far.
Nonetheless, Grinde, a beverage-industry salesman, says he’s increasing his stake. He sells BitMine options to help offset losses. He attributes his conviction in the company to the growing popularity of the Ethereum blockchain—the network that issues the ether token—and Lee’s influence.
“I think his network and his pizzazz have helped the stock skyrocket since he took over,” he said of Lee, who spent 15 years at JPMorgan Chase, is a managing partner at Fundstrat Global Advisors and a frequent business-television commentator.
