There are 2 types of collectors out there:
Collector A - Wants every variation possible and wants every variation recorded here. Therefore, to this type of collector, if sticker front X has back Y or back Z, they want both catalogued (and to find for their collection - usually).
Collector B - Treats the stickers as one set and the backs as a second, different set. Therefore, there are 3 types of stickers per team (diamond logo, hat, & logo) that means the sticker set has 78 entries. The backs, and I don't remember now ho many make up the all-star game photo so I'm just going to guess, say there are 20 different backs to make up the ASG photo. Then the sticker back set has 20 entries.
There seems to be a lot of Collector A types on here. :) (There was even some talk in a thread about getting the different backs displayed for the T-206 set.) With these stickers, as they were basically Fleer's response to not being allowed to put gum into packs (Donruss countered with their puzzle pieces), most wound up in the garbage cans with the wrappers. I actually saved mine, and will see what I have eventually and put them with my actual card sets when I dig through them and figure out what I have. I doubt I'll go after "variations" of these.
