Mexican Lobby Card: Godzilla vs. Megalon (1973)

I'm not sure if this was used as a lobby card, window card, or theater handout. The paper is glossy and thin and there's a space below the image to add theater information. Window cards have the space, but usually it's larger, positioned at the top, and the card's paper stock would be thick and rigid. However it was used, you can't beat robots and monsters doing a smackdown with Godzilla.
