A painting by David Bowie, originally bought for just $4 at a thrift store, is now projected to sell for more than $60,000.

In addition to being a passionate art collector, David Bowie was also a talented artist himself. His creations include nearly fifty portraits of musicians, friends, and even Bowie himself, which he painted in the mid-1990s under the title Dead Heads (or DHeads). One of these paintings, DHead XLVI, was recently discovered in a donation center in South River, Ontario, where it was purchased for just CAD $5 (USD $4.05).

As reported by NPR, the buyer initially did not realize that the acrylic painting featured Bowie’s signature on the back until after the purchase. They later reached out to Toronto’s Cowley Abbott auction house, which worked alongside Bowie autograph expert Andy Peters to authenticate the piece. Interestingly, Peters had previously come across an online listing for the same artwork in the early 2000s and immediately recognized it.

“I didn’t need to see the autograph on the back because I already knew, but the signature certainly confirmed it,” he told CNN.

Anything with the touch of Ziggy Stardust is bound to sell for more than $5 at an auction, and this 9.75-inch by 8-inch canvas is no exception. The auction house has estimated its worth between CAD $9,000 and $12,000 (USD $7,282–$9,709), with bidders quickly surpassing those figures. By Monday, June 21, the leading bid had already reached CAD $75,100 (USD $60,764)—far exceeding the USD $27,500 paid for another Dead Head in 2018.

The final price of DHead XLVI will be revealed when the auction closes at 2:15 p.m. EST on June 24. As for the identity of the person depicted in the painting, that remains uncertain.
