5 pieces Vintage Elegant OPTIC Glass Stemware Yellow, Topaz Cambridge

Description

Here are five pieces of vintage elegant glass stemware in topaz (yellow).
They are optic, with a draped type design and lovely stem as well.  The water measures 7 1/2" and the low champagnes measure 5 1/2".  They look like Cambridge Glass to me, but I have not looked up the pattern.
No chips or problems. Lovely.
