There are more:

CTP1 (Coastside Toys)


And oddly, both Sci-Fi Cards and Tom Breyer seem to have promos numbered SFP1, but with different backs and fronts !

UP1 comes in 2 versions, with and without Dealer Promo on the front

Tom Breyer has 2 promos, CTP1 and SFP1, both have the same fronts and backs, just different numbers on them

However, his SFP1 is totally different from Ed Webb (Sci-Fi Cards)'s SFP1, and his CTP1 is not the same as the one from Coastside Toys

Confused yet ?
