I didn't feel like hunting for the thread that discussed artists that sell signed merch on their own website, so I'm just throwing this in the mix:

An 11x14 photo taken by Chris Stein in 1977 of Debbie Harry and Devo - signed by Stein, Harry, and members of Devo. I guess they sold copies on a Blondie/Devo tour last year, and these were left over. I thought it was a decent price, so I couldn't resist ordering one. I think its a limited edition of 300 and I talked to Impact Merch - they don't have many left and can't get any more. (They also vouched that the autos were all hand signed, not copied on). Dig it.
