I have seen a zillion Iffy Club pins over the years. This is the only card on which the pins were originally issued with I have ever encountered. The card explains the nature of the club. The pin was attached to the card when distributed in the upper left. Apparently no one had interest in saving the card! I think this is a pretty neat well known pin-related ultra rarity.

5 1/2 x 3 1/2 inches.

Good condition.
