Would anyone here have an idea where I can get a value placed on my Miles Davis autographed poster? Long story short (and can tell the longer version if there is interest) he was in concert in Iowa City while I was an undergrad there and I was able to get this poster signed backstage. He sort of got "lost" in the moment and drew on it, a picture of himself looking back to when he was the young'un in the picture, then wrote "Miles" asked "who's this to?" and I said my name so he wrote "Mike", then said "You're a dog" and wrote "dog". There are two other musicians there but I don't know who they are. Below is a pic of the poster. Any help would be appreciated. Hmmm, next step...can someone help me post a pic?
