These are what the 3 different hologram variations look like.

First off, I can't say that I liked the stock this product was printed on. My guess as a printer is that this particular stock is easier to run through the press, keeping the presses rinning for a large project.

The quality of the set is generally great with the exception of the filler cardsI didn't really love the idea of 3 Favres or Sanders but give them credit for producing a set that was anything but safe. At the very least, all of the first round draft choices were included, at least the ones who were signed. The colors were bright and to me, this was the first generation of HD images.

I believe this set to be an important piece of NFL history. Lots of stars and HOFers. As to the inserts, I think we all knew that UD would be doing a Heroes set after the success of the Jackson set in baseball. The GB holograms were first rate for that era. The SP cards were a breakthrough idea at the time. They weren't just commerative cards, they were difficult to find to boot. I'm guessing that one or the other came every 72 packs.

All in all, no matter how much anyone criticizes this set, it was far and away the best set of 1991.
