Chiffon NFL Team Booster Decals
 

I recently picked up a lot of these booster decals produced by Chiffon, and was wondering if anyone knows anthing about them. They are approx 3.5" x 5.5". There is no date on them, but a couple details like single-bar face masks and old team logos may be indicators.

The backs are all identical and only mention how these were obtained and how to apply them.
