Anyone have any ideas for nibbles I could serve at a party that are 50s in theme? The party is during the day, so it is not a cocktail party though I do plan on serving Bloody Marys.

I'm looking for stuff that is delicious and edible but def has that retro feel as I'm hosting what is basically a Tupperware party for a good friend and we want to play up the kitsch of the whole thing.

Thank you.
