I "Dabble" in those, but only ones that I have a "connection" to/influenced or moved me in some way- e.g., Judy Garland, Lucille Ball, the (Broadway) Cast of the Producers (with Mel Brooks) and my only music one (Elton John, signed yellow Brick Road Album). That being said, I have given autograph gifts over the years to friends, family and acquaintances based on their personal favorites- so far Jackie Gleason leads that pack on those, LOL
