First up...I'm guessing a Panini?
2nd...a Google search shows someone calling this a 1979 Super Sticker, but it's different than mine than actual says "1979" and "Super Sticker" right one it (the one with red letters).
3rd...small sticker. The curve is just a curve of the card but it is cut very askew.
4th...a little larger than a normal card.
5th...a little smaller than a normal card.
6th...about the size of a regular card.
Thanks for any help!
