Vintage Jim Rumph 1973 Art Pottery Splatter Bird Tankard Mug Troll Raven Pooping

Gorgeous piece from artist Jim Rumpf. Chubby bird perched on the handle and popping on a troll inside the much. Exterior is a pretty matte finish. Bird does have a crack - unsure if it’s damage or just from the manufacturing process. This mug is meant to be art and NOT for actual use. Please review photos.
