Spook Shows were a big thing in the 1950's and 60's when everyone was monster crazy! This "Hollywood Monster Show" had the biggest monster stars appear live on stage with the Frankenstein Monster, the Killer Creature and the Mummy. I guess Dracula had a previous engagement and wasn't able to make the show.
I'm not sure where the Beyer Theatre was but I'm guessing it might have been Beyers in Excelsior Springs, Missouri, which has been closed for many years. I purchased this at an antique store here in Missouri, so it's a good chance that it's from there.
