Vintage Barware 1950s 60s Pink Elephant Cocktails Invitation 10 Cards NIP Unused

These are ten Pink Elephant cocktails invitation cards made by Rust Craft. They are still sealed in their plastic pouch packaging with header card that reads Rust Craft Invitations 10 Cards 50. I think that they date to the early 1960s, although they might date to the 1950s - the pink elephant was a popular theme for barware in those times. The cards measure 3 1/2 by 4 1/2 and come with envelopes in the package. A sample of the text on the back on the card is visible at the back of the package. Fun invitation cards from the golden age of the cocktail party!
