A simple, metal brooch with a modernist, art deco aesthetic.
The brooch is made of a silver-toned metal which I think is stainless steel and has a c-clasp at the back which all works perfectly.
Judging by the style and the clasp I think this dates to the 1930s-40s but it could be otherwise.
In very good condition, with some wear as can be seen in the photos.
55 mm long and 22 mm at the widest point.
