3 egg cups with black opaline glass hens Arcoroc 1980

Superb trio of Arcoroc egg cups in molded black opaline glass, each featuring a stylized hen forming the base and stem of the egg cup. Typical of Arcopal design from the 1960s and 1970s. Height: 7 cm. Very good vintage condition. Note: the beak of one of the birds is slightly "planed, " probably due to a shock, but this is barely visible (see the circle in the photo).
