This vintage fine bone china mug features a portrait of a wire-haired(?) terrier on the front and a collar and leash on the back. It was made by Rosina China Co. Ltd. and is marked Queen's fine bone china made in England. The mug has been used but shows no stains or damage of any kind. There is gold wear which puzzled me at first because it is on the handle and the rim by the handle. Then I realized that the previous owner had held the mug by the handle with a thumb resting on the rim. I can imagine someone drinking from the mug and remembering a beloved pet or with that pet close by. This is a large mug and will hold 10 ounces.
