The 1986-87 Fleer Sticker set is about as condition sensitive as they come. The stickers were seeded as the last card in each pack, meaning that they almost always came with a large coating of wax. The best way to remove this wax is by carefully rubbing it off with a pair of nylons (it sounds funny, but this will do the trick). These cards were also prone to some major cutting issues at the factory, which resulted in many of them resembling more of a "diamond" shape rather than a standard 2 ½ x 3 ½ card. The Jordan "Rookie Sticker" is the crown jewel of this set.
