I found this at a local antique store. I have seen several of these cups on ebay and I think they are called a stirrup cup. The ones I have seen are usually marked with Gucci on one side and Italy on the other. The only markings on this cup is Italy M/M. This is located on the back of the head of the animal. I would like to find out who made this cup and any other information. I think this is a really cool looking cup and a great conversation piece. Any help and apprasial would be greatly appreciated!
