Pair of Terre de Fer plates, Birds model, Manufacture de Carouge

Superb pair of matching Terre de Fer plates, model Birds, in good condition despite their age, see photos, stamped on the back, (blackbird?) and engraved Yvoire. Better than a pair of identical plates, these are matched: it's the same model but the birds are different, a couple on the first and 4 small birds on the second. It's wonderful! Diameter 23.5 X height 2 cm.
