Gorgeous Swirly Deco Black and Gold 1940s French Hair Clip

Lovely swooping swirls in gold frolic across this shiny black hair barrette.
It is 9cm long and 3.5cm tall and slightly curved, with a little
comb on the back to make sure it does its job effectively.
I only have a few of these and there is an odd bit of wear on the gold swirls.
It comes on its original French display card on which is proclaimed
