Not sure about this one.  I got this from a friend who just sent it to me as a gift.  Apparently he got it when he traded or bought from someone else. He noticed my Wonka small collection and thought I might like it.  He says it's David Wolper's signature, but the signature looks like Danny Walper. I didn't find anyone famous by the name of Danny Walper or Wolper, so I have no clue if this is accurate.  It's signed to someone else, so I may rewrite Mr. Wolper to get a signed photo. If anyone knows about this, let me know?  Email me at Mr. Wolper was the producer for Willy Wonka and the Chocolate Factory.
