This is a mug shaped like a skull missing the lower jaw. There was a previous version of a jawless skull designed by Mr. Bony and manufactured by Gecko'z South Sea Arts, but it was a bit more stylized. Gecko'z version is more realistic and features a more defined nasal cavity, more rounded/smaller zygomatic bone (part of skull beneath eye sockets) and smaller more realistic teeth. It is not marked "Mr Bony" on bottom. This version of the mug is hand painted.
