Edgar Allan Poe's Tales of Mystery and Madness Easter Egg - Vincent Price Gravestone

On the back cover of this book, there is an illustration of a graveyard. One of the gravestones, half covered by the cat's tail, reads "V.P. 1911-1993". As we horror fans will know, this is the legendary Vincent Price, who the illustrator, Gris Grimly, lists as one of his influences.
