Ah, a sweet memory of the Eiffel Tower in Paris. This adorable pewter style hand mirror measures approx. 5 1/4" long. I do not think it is very old, maybe from the 70's or 80's. The mirror side has a couple of minor surface marks from use.
It reads along the top curve: Souvenir de Paris La Tour Eiffel
A great little piece of Paris for your vanity or purse.
