Royal Doulton, The Red Queen small character jug, from Alice in Wonderland. This mug, Doulton #D6859, is 4.5" tall and carries the Royal Doulton mark on the base, along with the signature of its designer, William K Harper. It’s in excellent shape, with no chips, cracks or other damage. It was introduced in 1990 and discontinued in 1991, so there aren’t many of them around.
