A Banksy piece fetched $12.9 million in an auction Tuesday — and the winning bidder can pay for the pricey pop art with cryptocurrency.

The anonymous artist’s “Love is in the Air” is the first physical piece of art sold by a major auction house accepting crypto as a payment option, according to a tweet from Sotheby’s.

The protest image — which shows a protester winding up with a bouquet of flowers in hand instead of a molotov cocktail — was sold after a 14-minute bidding battle with four participants, Sotheby’s said.

The auction house announced in March it would auction off a series of non-fungible tokens, or NFTs, which are digital assets that represent ownership of virtual items like art and sports memorabilia.
