Antique Silver & Enamel authentic Green Yellow Butterfly Brooch

A wonderful antique silver and enamel butterfly brooch.
Made, probably in England, in the first half of the C20th.

The brooch is stylised and simplified, the wings a fresh, bright authentic green and the body and spots are in yellow.

The brooch measures
4cm between the top wingtips, 1.8cm between the bottom ones and is 3.5cm long

The brooch is marked Silver on the back.
It's in good antique condition. The enamel is a little uneven around the edges, and on the yellow body, but this is not damage. There is, however, a flake of enamel lost from the top of one wing, where the yellow spot looks a lot paler.
