Here's a thoroughly mesmerizing yet utterly confusing Mexican lobby card for a horror movie; I'm just not sure which one. El Vampiro did not star Melvyn Douglas and Lionel Atwill (I'm assuming the horribly mangled "Leonel Alwel" is actually Lionel Atwill since I can't find any reference to an Alwel.) They did star together in The Vampire Bat, but that doesn't explain their names here, except for the vampire theme in both movies. German Robles and Abel Salazar star in El Vampiro, and, according to Wikipedia, it's the first vampire movie to show some tooth, which corresponds to the sinister illustration. The inset still--and my memory's vague here so don't stake me if I'm wrong--is from El Vampiro. I wonder if patrons expecting to see El Vampiro were actually duped into seeing The Vampire Bat? Then again, if this lobby card is truly for El Vampiro, why sell the movie with two American actors when German Robles and Abel Salazar were top name draws themselves? I love a mystery!
