Gallery tweeted that Depp’s “debut collection ‘Friends & Heroes’ is now officially sold out.”

“This world-first release proved to be our fastest-selling collection to date, with all titles selling out in just hours,” the gallery said.

All 780 prints were quickly marked “out of stock,” with the sale making an estimated $3.65 million in the sale.

The collection “saw him focus on people he has known well, and who have inspired him as a person,” the London gallery said.

Depp’s debut collection focused on “people he has known well, and who have inspired him as a person,” including Liz Taylor.

Art was Depp’s passion “before acting, and before music,” the gallery said.

Depp’s sold-out works including an image of his “”dear friend Keith Richards, who inspired the mannerisms of the infamous Captain Jack Sparrow.”

The collection also included an image of another rock legend, Bob Dylan.
