A few thoughts from opening these boxes:
- He enjoyed the Bowman Chrome cards ("These are so SHINY")
- The Pop-Up Donruss cards were a hit, too - He's got about 20 popped up on his desk right now
- An unexpected one - the 1992 Topps came with a scratch off game card in each pack. That ended up being quite the diversion as we figured out how to play the game. He had a lot of fun with them.
- I vaguely remember those game cards being the reason that the market remains flooded with 1992 Topps Gold "Winners" cards (I believe it involved something really high tech like holding the game card up to a bright light).
