St Louis Crystal Champagne Glass Cocktail Coupe and I think this is Gavarni Pattern ... Unsigned piece and I think this is circa 1930's - 1940's ... In last two pictures I'm showing light scratches and in the other three pictures I'm pointing out tiny nicks  .. Overall beautiful old piece .... Pictures are part of the description .... Please ask all questions important to you and please see pictures for all details and measurement ....Thank You.
