I found this tea cup at a church sale and have spent a week searching for information on it. Does anyone know anything about this ? It is stamped with a green MR stamp on the bottom. The cup is very tiny and petite, about 2″ tall and the porcelain is very thin and not heavy. I narrowed down from the stamp that it may have been manufacured between 1891-1896.
