I don't know if this is of interest, but I've just released the first half of an OSR bestiary card line, covering letters A-J. The 6"x6" cards contain all pertinent information such as armor class and hit dice, but also include full details on treasure, saving throws, and "to hit" numbers! The cards are directly compatible with Labyrinth Lord and the Basic/Expert set from 1981. They are also easily used with Adventurer Conqueror King and Swords & Wizardry. You can take a look at DTRPG. I've thought of doing this for C&C, but I have no idea if there is an audience (so to speak). Anyways, hope someone likes them!
