This is the APS Tiki 'Monkey mug' (if my translation of their German wholesale website is correct). I'd call it a monkey head mug if it were up to me. 4.5" tall and 5" wide sideways ear-to-ear. Seems to come in a variety of brown glazes - presumably to represent different species of monkeys/apes - but you seem to get no choice in which colour you receive.
