I picked up this awesome card from the last Card Show I attended... I didn't know anything about the set, but the dealer (a good guy that I trust) told me it was from a set that featured randomly inserted Willie Mays autos on the back of some of the cards. The back of cards 46-90 make a puzzle if you can collect all of them. I've tried to search for this card (or another similar one) line that has an auto on the back, but haven't had any luck. Is anyone familiar with this set?

From what I have been able to glean, it's from the 1984 ASA Willie Mays set, ordered exclusively through Renata Galasso's Hobby mail order operation. I found other cards from this set online, but nothing like the auto I found.
