Oval Football stickers
Another type of sticker from my B.A.B. database, though these are unlikely to be issued by B.A.B. They were more likely to have been issued by Northern Trancessories.
Blackpool were in the First Division in 1970-71 and Carlisle United were there in 1973-74, while Portsmouth spent most of the 1960s and 1970s in the Second Division.
