I had that card as a kid. I think I bought it at a flea market for like $20 or $30, which at the time was a really expensive card. Then I mailed it in for an autograph and never saw it again. I was devastated. Knowing what I know now about Sandberg, I'm sure it never even got to him. I eventually ended up getting the slightly cheaper Fleer rookie card as a replacement, and only recently got another Topps card when my wife bought one for me as a gift a few years ago.
