Next, we get into uncharted territory as I've never seen any of the movies listed below. Here we have Mexican and Spanish posters for Santo vs. the Zombies, Santo vs. Baron Brakola, Santo vs. Frankenstein's Daughter, and finally, Santo vs. the Riders of Terror.
Here we have a couple of interesting posters. The poster for Santo in the Hotel of Death has sort of a film noir feel to it with a caped, skull-faced monster wearing a fedora surrounded by sexy women. The poster for Santo and Blue Demon in the Land of the Dead rips off graphic elements from Vincent Price's House of Usher, (note the woman in the coffin). Finally, Santo's pal Blue Demon gets into the action with Invasion of the Dead and Blue Demon vs. the Satanic Power.
