vintage opaline milk glass decanter & glasses, Portieux Vallerysthal white opalescent glass

Vintage French opaline glass decanter bottle and four small goblets - these are unmarked, Portieux Vallerysthal made in France. This is such a lovely set!

There's a chip to the bottle rim (see photos), but aside from that, these don't look as though they've had much if any use. The decanter measures about 11 1/2" tall to the top of the stopper, and the glasses are about 3 1/4" tall overall.
