Silver leaf pattern drinking glasses which are NOT Libbey Silver Foliage - these are not signed, and I've had an impossible time researching this design as it seems as though Silver Foliage is all that ever comes up in a search!
These look like Culver or Fred Press to me, and I know that sometimes their designs are not marked. I don't think they're Georges Briard, I think I've checked all the catalog reprints and can't find them there.
These are highballs, a set of six tumblers 5" tall. They're all in good condition, very little wear, nice and glossy.
