Picked these up back in the eighties from booths in the mall or such.  Anyone know how many of these posters exist?  I really like the D&D one.  It's cool looking over the '83 catalog and seeing how many of those games and items never made it past the initial fake pictures put in the catalog (it was apparently quite common to get an artist to draw "screenshots" of a game before work on it had even begun, for the catalogs)
