This white mug is shaped like the Japanese maneki neko, or beckoning cat. The cat has one paw raised and is believed to bring luck.
This is a Dynasty Wholesale design similar to the Orchids of Hawaii design that preceded it. The oval on chest is a bit bigger and other details make it stand out from the Orchids version, however. These are usually marked "Made In China DW 127" on bottom, but some of this design just have "Made In China" and some have nothing on the bottom.
Dynasty also started making a pink glazed version relatively recently.
