Here are four signed caps — Honus Wagner, Rogers Hornsby, Joe Jackson and Ty Cobb — that come with letters from the late Barry Halper verifying their authenticity. Now I'm no autograph expert, but two of the caps, the White Sox and Cardinals, feature styles that came out after the players died. Seeing this, I can't help but think of all the fake stuff Halper supposedly sold to the Baseball Hall of Fame. Anyway, I'm curious what others think of these. I've never seen anything like them.
