Got this from the Mai-Kai where it's being sold as their 'Mai-Kai Hot Buttered Rum Mug'. It's a nice mug with a floral pattern and the same green/brown glaze both inside and out - but there are no indications that it's being manufactured specifically for the Mai-Kai. The base is unmarked aside from a generic 'Made in China' sticker. pittsburgh paulie has one in his collection too - and he's also included a snapshot of the Mai-kai menu which features the mug. 3.25" tall and with a 3.25" diameter.
