Wine glasses from the 1940

Here is a batch of 5 absolutely delicate wine glasses. They date back to the 1930s or 1940s. Their high, fine line is underlined by the engraved patterns of geometric shapes. Their foot is atypical with its cubic lines, instead of the round and soft shape of classic lenses. They would be absolutely delightful on a festive table, for an aperitif or a late meal... They are in perfect condition except for a microphone on the foot of one of them, visible in the photos. 7 cm diameter, height 17 cm.
