I busted a half-dozen packs and here are some of the highlights:
Fight Club au Naturale
My Little Pony
The World's Smallest Man
Some Guy Trying to Look Like Burt Reynolds Whilst Wrestling a Rather Large Snake
Let's not forget this guy's relatives:

Truly, this set offers a mix-bag of classic cards. If sports is your thing, I pulled some Chicago Bear and a Cricket player, so there's some of that too.
Six packs in and I'm a little over half-way through the set. Packs come with ten cards and there's 100 cards in the set. There's no inserts to be found but according to Jeff Allender's Checklist, there's also four promos to compliment the set. ProSet also made a custom binder.
Guinness Book of Records, like all ProSet products, should be considered junk wax. Boxes can be found on eBay for less than $5 while an entire case of 20 boxes can be had for $32 plus shipping. I suspect one box, which can make more than three sets, should suffice.
