Beautiful modernist brutalist gold plated pewter brooch signed by Gilles Vidal, a French Canadian designer. The brooch is just under 2" x 1 3/4:, mark of Gilles Vidal on the back. This is unpolished, wear consistent with age - very nice condition.
See my listings for more Gilles Vidal pieces, I combine on shipping.
Here is some information that I was able to find on Gilles Vidal. Canadian modernist designer a Montreal based designer, who worked in pewter and was in production in the late 60's to early 70's Vidal's designs were sophisticated and dainty. It was also said that Vidal had concocted his own pewter formula which provided an ability to work finer designs that still held their strength, as pewter, a lead alloy is very soft and finer work can bend easily and be damaged
