I found this Mexican lobby card for Santo Contra Los Secuestradores (1973) primitive in its layout, but still effective. Hints of action, villains, and women with and without guns. Looks like fun to me.
A fantastic Mexican lobby card for White Pongo (1945). Could this be the missing link between man and ape?! Nah. Just a man in a gorilla suit. But I'll keep searching for you. Ray "Crash" Corrigan plays the ape. Naturally. Aguirre Tinoco drew the ape in his distinctive artistic style.
How can you not love this goofy Mexican lobby card for Conquistador De La Luna (1960). Here's a variation of it that's not as colorful.
