I had always assumed that there were only 5 different 1977 star wars pack variations. Today I learned that there are two different series 5 wrappers and a number of series 1 "fun packs" with 2, 3 and 4 cards each. Does anybody know anything more about these "fun pack" variations and is there any way to distinguish them except by pack thickness?
See PSA link below:

I have the series one fun pack. Same wrapper just two cards I believe. Series 2 also has two wrapper variations. The pink helmet and the red helmet.
There's also a 2nd Series pack with English on the front and French on the back.
