Almost 5" across and about 1-1/4 inches tall.
Hand painted at de Porceleyne Fles in the Black Scratch style with cherry blossoms. This form of black delftware was only made from 1957 to the mid 1960's. Production was expensive and therefore quite limited.
Dated 1966 with the artists initials KOO.
Excellent condition with some minor crazing.
