No, I don't have any. I've never been "into" autographs myself. Never really understood the appeal of having an autograph, unless it was a special "set" of them, say, like a full set of Presidential Autographs of all the US Presidents. Now THAT would be impressive!
But anyway, I just got to thinking about how inherently COOL it would be to have a full set of McQuarrie Concept Figures autographed by the man himself. Then I wondered if A) he was getting a full set of the figures from Hasbro and B) what he thought of seeing his conceptual work turned into 3D versions by Hasbro and other companies.
