The Leopard Men Mexican Lobby Card

I'm not sure what movie this may be from, but the lobby card design indicates it could be anywhere from the 1930s to 50s. Dorothy Short did Call of the Savage in 1935, but I don't see a credit for Paul Gifford on IMDb; and the inset scene with Amazonian women looks more like a 1950s movie than earlier. Anyway, the card illustration is what drew me to these cards. That, and the Amazonian women, of course.
