Jason Lee has offered a $25,000 reward for the return of photograph of the late Dennis Hopper.

The 'My Name Is Earl' star took the picture of the 'Easy Rider' actor - who died last year after losing his battle against prostate cancer - and gave the black and white Polaroid to the THIS Los Angeles exhibition to put on display.

However the photograph was stolen over the weekend and Jason is now offering $25,000 for the sentimental snap to be returned, no questions asked.

A post on the exhibition's website says: "We have some very unfortunate and sad news and we need your help to solve it. Last night towards the end of our These Friends opening (after the crowds had left and we were cleaning up) someone stole a piece off the wall and bolted out The Front door.

"It was Jason Lee's one of a kind 8x10 Polaroid of the late Dennis Hopper. The artist is putting up a $25,000 reward to anyone who brings it back to us. This is a very sentimental one of a kind piece for obvious reasons. The thief can come forward anonymously and charges won't be pressed against him. Please get the word out and help us get Jason's art back.

"This piece was not for sale, it's extremely sentimental to Jason and he just wanted to share it with the art community by having it in the show."
