I love this poster for the 1968 film “Destroy All Monsters”. There are several others out there, but this one has that great 50s/60s vibe and just oozes chaos.

Godzilla attacks New York!
Rodan devastates Moscow!
Manda obliterates London!
and Mothra smashes Peking!
EVERYONE is pretty much screwed!

I also dig that the monsters are listed along the bottom, where the actors would be in a regular movie.

STARRING GODZILLA as GODZILLA!

The trivia behind Godzilla’s name?

Godzilla’s Japanese name, “Gojira,” is the combination of the words for gorilla (“gorira”) and whale (“kujira”), purportedly the nickname of a portly Toho publicist. His American name is simply a phonetic approximation.
