thanks, rick. i found the seller in my eternal search for an authentic robin williams autograph and i feel pretty confident that i found it. it's a nice "flubber" publicity still. not my favorite movie by any stretch of the imagination, but i'll take what i can get. ;)
I don't know what his sig should look like but saw this whilst I was looking at some other stuff from another dealer that I was familiar with. It isn't cheap though. See what other people who know what his sig should be like think of it. I hope you find your Williams.
