Correspondence between James Warren and Dave (Photon, Gore Creatures) Ludwig on his potential contributions as an FM cover artist. (It didn't work out.)
Another flyer announcing Fantastic Monsters #1. The other side is a reproduction of the first issue's front and back cover and the inside back cover. When folded (in thirds) the flyer is magazine size with the color front and back covers showing.
Aurora and FM had an ongoing relationship for many years and during the mid '60s this coupon could be found in the boxes of their monster models. It offered a free copy (i.e., random back issue) of FM if you sent in the coupon with 25¢ for shipping. Probably not a lot of these have survived, as they would have been used. These coupons have also been found in the SPP monster wallets.
