In 1860, Englishman Harvey Adams came up with an unusual invention, "the moustache cup". This had a ledge or shelf, called a moustache guard, across the cup. The ledge had one semicircular opening against the side of the cup. The pampered moustache then rested safe and dry on the guard while sipping a hot beverage through the opening.
The name on the bottom of the cup looks like Leuchthuar Germany.
