When I was collecting test issues 20-25 years ago, I had only one 1970 cloth sticker, AL Playoff Game 2 (Boog Powell), in ex-mt condition; I also had both 1976 cloth stickers (don't recall which type), however mine had the card front images reversed ("REYD YFFUD") and they were slightly oversized with extra-wide borders on one side.

I recall first seeing the 1972 cloth sheet(s) in Willow Grove around 1984/85 and buying a few of those commons after a sheet or two was cut up, and I recall quite a bit of arguing among dealers and collectors as to whether those sheets (and the discs sheets which also surfaced around that time) should be cut...
