My favorite Batman movie is the 1966 one, featuring the cast of the TV show. I've taken quite a bit of flak from "Dark Knight" worshipers. I discovered this poster on another retro website for the 1966 Batman movie. I'm guessing by the strange coloration that this poster is from a foreign country or Batman washed his tights in the same load of clothes with Robin's red vest.
NOTE: When I uploaded this an enlarged it, I did notice some of the words are in a foreign language.
