A slew of them on Google Lens, but only one I saw had a saucer with it. I wonder if it's just one somebody put with it, or they originally didn't have saucers?
Love the old battleship thick 'Restaurantware'. I used to have 5 or 6 of these old logo'ed diner cups- tuff to find cheap these days !
I sold a Dunkin mug awhile back, but mine was newer with only the name on it no graphics. That was when everyone wanted that mug, but I think Deb's is sellable at the right price at her garage sale and tell the buyer she or he can get a good price if they are a reseller.
Another "restaurant" style cup & saucer with crown motif. Made by Sterling China. Google Lens indicates it was used in the Hotel del Coronado.
