What is a moustache cup?

A moustache cup is a specialized drinking vessel designed in the 19th century for men with prominent moustaches. It features a ledge or guard along the rim to prevent the moustache from coming into contact with the liquid, thus keeping it dry and clean while drinking. These cups were particularly popular during the Victorian era when well-groomed facial hair was a fashion statement. Today, moustache cups are often considered collectibles or quirky vintage items.
