Yes, he did always draw a caricature of Mickey Mouse when he signed. Got his autograph many decades ago, at DuQuoin, I think. Actually, I got it multiple times, but I have a small notebook that I kept for what I considered my permanent autograph collection. I got several autographs over the years on racing programs, too, from many drivers. I was fortunate to get Don Branson and Jud Larson to sign at DuQuoin in 1965. DuQuoin was a good place to get a lot of autographs back in the day.
