A Vincent Van Gogh painting was sold for 21.7 million dollars at an auction on Thursday only to be erroneously sold a second time for 20.3 million.
Auction house Sotherby’s said a glitch with its online system during the sale allowed for the double sale.
The painting has been kept in a private collection for more than a century prior to sale, away from the public eye.
The identity of the buyer has not been revealed.
