Invisible art sells for $1.2 million…

They kept the receipt.

Thought paying $120,000 for a banana on a wall was extreme? Earlier this week, a receipt for a piece of “invisible art” eclipsed expectations after being auctioned off in Paris for nearly $1.2 million.

“This work is guaranteed and received an irrevocable bid,” auction house Sotheby’s wrote in its catalog regarding the pay stub, which went for $1,151,467.40 — over twice the estimated price of $551,000.

Naturally, paying money for nothing might seem strange. However, the receipt was a rare remnant from “Zones of Immaterial Pictorial Sensibility,” a mid-1900s exhibition series in which pioneering French performance artist Yves Klein would sell vacant rooms to collectors in exchange for gold bullion.

The radical visionary would then invite collectors to burn the receipts and dump half the gold into the Seine River — the logic being that in doing so they’d become “definitive owner” of the “zone.”
