i took a quick look for something about this (but i'm a lazy bastard and made it real quick) and didn't see anything.
so, how do the prices on the vintage palitoy figures compare with the kenner ones? i have a vintage boba fett rotj 65 back on a palitoy card, or at least i think it's a palitoy card, because it doesn't have a kenner logo on the front, and the mail in offer on the back for a chewbacca bandolier has a uk address.
according to this
site it's a 65d cardback.
