A little restaurant ware for my tiny collection. A saucer? That's my best guess. It's tiny.
Bonus: From Restaurant Ware Collectors Network:
[Mayer produced] this custom pattern in 1959 for a restaurant in Manhattan. The Forum was one of a series of theme restaurants established by Jerome Brody in the 1950's.
Fitting for me to post about a little plate today, April 3rd. It is my mom's birthday and she is responsible for giving me the thrifting gene!
