I must say that Upper Deck basically started all this insert card craze. First there was the 89 UD Griffey that everyone wanted to pull. Then in 1990 they got the ball rolling by releasing the UD Reggie Jackson Heros Auto card, which people were paying up to $1,000 for back then. They started the insert card revolution with that Jackson card, then Donruss caught on in 91 with Donruss Elite.
