Monster Cards Wikipedia
The Monster Cards were a DM's aid, with each set containing twenty 3" by 5" cards, each with a color monster illustration on one side and statistics on the other side. The DM could show the monster's picture to the players, while keeping the statistics hidden.
The Monster Cards Sets 1 through 4 were designed by the TSR Design Staff, with art by Jeff Dee, Erol Otus, Jim Roslof, Darlene Pekul, and Bill Willingham, and were published by TSR in 1981 as sets of 20 color cards in a small clear plastic box. Additional contributing artists included Jim Holloway, Harry Quinn, Steve Sullivan, and Dave LaForce.
A second group of four sets was tentatively scheduled for release in 1983, according to Harold Johnson, and those sets would have included several monsters from the Fiend Folio book.
