The art retailer posted a photo of Depp working on a portrait of singer Bob Dylan.
It said that the collection of prints called “Friends & Heroes” was “a testament to those he has known well and others who have inspired him as a person”.
The gallery quoted Depp as saying: “My paintings surround my life, but I kept them to myself and limited myself. No one should ever limit themselves.”
The works depict Dylan, the late actress Elizabeth Taylor, actor Al Pacino and Rolling Stone Keith Richards.
The gallery chain later posted a tweet saying that “Johnny Depp broke the internet” and its website had crashed due to demand.
#JohnnyDepp broke the internet! Website will be back up soon.

All the prints were marked as “out of stock” by Thursday evening. There were 780 pieces of art.
Buyers paid £14,950 for a set of all four framed prints or £3,950 for a single print.
Depp in June won an award of $10 million in a defamation case against Heard in the United States, while she won $2 million in damages after counter-suing.
Heard is appealing against the verdict of the jury trial, which was live-streamed to millions and featured lurid and intimate details about the former couple’s private lives.
Depp previously lost a libel case against the British tabloid The Sun in London in 2020 for calling him a “wife-beater”.
In another creative venture, the actor this month released an album with English rocker Jeff Beck.
The record has been poorly reviewed by critics but broke into the top 40 in the UK.
