This sweet demitasse cup and saucer reads ROTARY COFFEE COMPANY with a wing design, all in black. A maroon stripe encircles both pieces. Sterling China manufactured the set between 1930s-1950s.
I've been unable to track down any info about this company. It could have been a coffee supplier and distributed these sets to their clients. Or if could have been a coffee shop, selling tiny cups of espresso and pastries. Regardless, it's a cool set.The cup stands 2 1/2 inches tall and the saucer measures 4 3/4 inches in diameter. Near MINT condition!
Great addition to any diner collection.Thanks for looking!
