Jason Lee is offering a $25,000 reward for the return of an original Polaroid photograph he took of the late actor Dennis Hopper that was stolen from an art show in Los Angeles on Saturday.
The My Name Is Earl star, 40, is said to be devastated over the theft of his one-of-a-kind, 8-by-10, black-and-white photo of Hopper, who died last year. The reward will be given for the safe return of the sentimental piece, no questions asked.
The photo was on display at a gallery in the Highland Park neighborhood of L.A., where a six-person artist collective called THIS Los Angeles was having an opening on Saturday. After the show, someone grabbed the photo from the wall and ran out with it.
Anyone with information can call THIS Los Angeles at (323) 747-5301 or e-mail firstname.lastname@example.org.
