Bob: The Cardboard ones do not have backing and are not scored. Here is a pic of a Cardboard back:My cloth version is scored and has backing. You can tell it is cloth even in pictures. I suspect you have the glossy ones and I may have found a pic of those. It also shows the Rub Off Game cards that came with it.Compare the scans to my Cloth version (Cloth on left, Cardboard on right:And there is a Football proof version as well:There also appear to be three wrappers for this set:1) "Cloth Stickers" version2) "Stickers" version 3) "2 Glossy 1 Cloth" version Here are scans of the first two, I did not save the last and cannot find it on the web right now. I believe #2 may be a transition wrapper. It is also possible the set was issued in '73 and '74; there has always been disagreement over the date.1)- a wrapper and pack::2) Note the word "Cloth" is gone3) Need a scan of this one!
