Art Nouveau Pewter Card Dish Circa 1890

This is a rather unusual and fairly large piece at 9 /2" in length. The piece has no makers markings that I can find. Condition is good bar one small split in the pewter at the end of the leaf. The definition on the cast is also pretty good and the subject matter is interesting what with the Angel playing her lute and the frogs sitting on the leaf either side of her. Could be European I feel and definitely a period piece Circa 1880 - 1900.
