7 old knife rests plate holders bamboo model Portieux

Set of 7 (plus one with a discreet chip) antique plate risers, moulded glass. Shaped like a step, hollow underneath, they slide under the plate allowing it to be tilted more or less to elegantly sauce asparagus and artichokes. According to a model almost similar to that of Baccarat present in the 1916 catalogue, they are all signed PORTIEUX. IN PERFECT USED CONDITION, without cracks or chips, see photo. Width: 5 cm at the widest, 3 cm at the narrowest. Length: 7.3 cm. Height: 2 cm at the highest. Other lovely items in my other sales.
