This ceramic mug from Tiki Lin features a standing Ku playing a yellow ukulele. A thick shiny brown glaze covers the outside and inside of the mug, but there's also a green palm-frond skirt, sometimes a green frond spray above the eyes, and he's standing on grey stones. The upper rim has a serrated edge.

This mug is part of a series of musician mugs available on Amazon and other barware sites - there's also a drummer, saxophone player, keyboardist, and electric guitar player, all using the same sculpt.
