This is darling! I'm not sure if it belonged to a children's tea set, or if it is actually an espresso cup, or what. It's that size, probably doesn't hold more than 2 oz. It's just shy of 2 inches tall and is 2 inches across. I've used it as a tea light holder, toothpick hold, q-tip holder... things like that, It has no markings. The gold is worn a little around the top edge.
Sweet and a little shabby. Just waiting for you to give it a special place in your heart and home.
