I'm working on a collection of Houston Colt 45's / Astros signed Topps base cards. Not sure that I'll ever get them all. It's a lot of fun though. I live in the Houston area so I get most of the current player sigs from team sponsored events. I've been successful getting a lot of the older players through the mail. Here's a link to my collection so far:
