By now, FKS had issued at least eight UK league sticker collections, dating back to the late-1960s. This was the first to feature a Villa side. The stickers themselves were designed to be glued along the top edge only, so that when in-situ, they could be lifted off the page as if on a hinge, to reveal biographical info on the player in question printed in the album. These stickers are unsurprisingly among the rarer of the Villa squads.
No gum - just a designated strip at the top where glue can be applied.
