Autographed Hostess cards or panels?
 

I've had this panel for a few years, I am sure the Brock is good, as I have many of his autos, and think having Rivers and Nettles as signers makes for a cool piece.

What other Hostess autos are out there?

Nice. I have a few with 2 signatures, but don't think I have a complete one. I got Fergie Jenkins on a panel myself a few years back that I enjoyed getting.
