Inside this old box of nonsense was an unassuming black three-ring binder completely full of card sleeves. And they are awesome.
I'll apologize for the glare or texture on some of the cards. Having been in those sleeves for the better part of twenty years, I didn't want to risk taking them out of the sleeves. With my luck, they will be stuck to the insides of them.
I don't know how my 12 year old self didn't completely lose his mind over these, because I'm absolutely tickled by them. I have a big love of play-aids at the able, and these are just wonderful.
I've got about 300 of these in total, it looks like. Whomever owned them before I did must have bought them in booster packs, as it seems TSR released 3 sets of 750 of them. Now I have an overwhelming need to track down and purchase them all, just to have them.
