This is a humorous design featuring a frog encyclopedia with illustrations of various frogs: bird frogs, bullfrogs, toad frogs, and common toads. This item is about 30 years old, and there is some chipping on the whites of the eyes of two of the frogs, so please check the photos. The material is not ceramic, but the item is sturdy and I think it can still be used. Diameter: 10.5 cm Height: 5.5 cm
