And before you-know-who asks, yes this is definitely in your trade pile.
Fleerfan got it right, This is a 1997 Pacific Card-Supial card of Jose Canseco with a teeny little Mark McGwire stowing away in Jose's backside. Card-Supial... marsupial... it's like a little Kangaroo pouch, get it? Yeah, I think it's really stupid too. Here's the back of Jose's card unencumbered by mini-card parasites.
And here's the Mini-Me of Mark McGwire.
Notice how Pacific matched the legs on Jose and mark so the mini picture fits seamlessly in it's mother pouch. Now that's quality. In a time of increasingly absurd chase cards, Pacific was always on the cutting edge with their insert inanity but I have to admit this is one of the weirder ones. It is kind of nice to pull a card that's two cards in one even if one is tiny Cracker Jack prize sized. Only thing is that they didn't put the player's mini card in with the big size card, they were always two different players when you pulled them from a pack. The back of the card goes as far as to state:
"Complete your Card-Supial™." Collect the little Jose Canseco card and place it in the Card-Supial pouch!This was easier said than done as there were 36 cards in the set, each with a big and mini version, all seeded at the typical one in 73 packs or whatever Pacific odds. If the chase card wasn't bad enough, now you had to chase another chase just to get a non-mixed up card. At least the pairing of the Bash Brothers was cool, even if Jose was in a Sox uniform at the time. The front is actually a really slick looking design, with a big swing swoosh for the name and foil rays radiating from the player as he presumably bashes a homer. I wouldn't send this into PSA though as both the big and mini cards have permanent creases where the mini was jammed in at the factory, which is found on all cards from this set. It's a nice card from the Golden Age of goofy-assed insert sets though, and I hope it will be enjoyed by our resident Canseco Completist, although I apologize in advance if you go nuts trying to find the mini card.
