A thief walked into a San Francisco art gallery and casually strolled out with a $20,000 Salvador Dalí etching in tow, according to new reports.

The suspect swiped the famed Spanish surrealist’s hand-colored artwork, titled “Surrealistic Bullfight: The Burning Giraffe,” from the Dennis Rae Fine Art Gallery around 4:30 p.m. Sunday, gallery associate director Rasjad Hopkins told KTVU.

Surveillance video obtained by the station, from the Handlery Union Square Hotel next door, shows the alleged thief walking at a relaxed pace — artwork in hand.

Hopkins told the station he was only about 20 feet from the pricey piece when the man took off with it.

“I turned my back to do something or talk to somebody,” he said. “I was in the back of the gallery and when I turned back, it was gone. Bam. Just like that.”

“It was a tall guy, wearing a typical hat, a colorful shirt. He was heading down the street with it under his arm. I’ve never seen him before,” Hopkins added. “I was upset. I couldn’t sleep last night. I felt so bad about it.”

The 20-inch-by-26-inch piece was displayed as a “showcase item” during the gallery’s special Salvador Dalí show, Angela Kellett, gallery director of Dennis Rae Fine Art, told ABC 7.

“It’s quite important as far as the period of etchings,” Kellett told the station. “It’s very, very well known. It’s a beautiful piece. It was inspired by Picasso first.”

The etching would normally have been secured to the easel, but the lock and cable were also mysteriously gone, the director said.

It wasn’t clear whether the suspect had previously entered the gallery to cut the cable, or whether he quickly sliced it in the half-minute before he walked out with the piece.

Kellett told the station this isn’t the type of artwork that typically goes up for sale on eBay.

“I think that people would know,” she said. “It’s a very small edition of etchings, so the number, we know exactly what piece it is, so now it’s a very hot item.”
