This is a small Royal Doulton porcelain figurine of the Mad Hatter character from Alice in Wonderland. It is part of a limited edition collection, with only 500 units produced. The figurine is a Character Jug with a glazed finish and stands at 4.5 inches tall.
It features colorful detailing and is an original British design by Royal Doulton. Please see my other Royal Doulton Toby's.
