My son collected Canseco as a kid and had quite a collection. This site was a good reference back then:
http://www.canseconet.com/
He had a funny experience with him when getting his autograph at a show. He asked Jose to sign a kids Canseco book "To Ben, Thanks for being a fan."
I stepped back to take a pic of my son at the table with Jose, and as he was handing the book back to my son, his handler grabbed it, pointing at it to Jose. I'm confused thinking has he never seen this book before? Then Canseco gets this confused, "boy am I a dumbass" look on his face, picks up the pen and signs it? Turns out that he was so focused on signing exactly the way my son wanted, that he forgot to actually sign his name! It was pretty funny, to say the least!
So, do you just collect cards, or anything and everything Canseco?
