Set of two ironstone deep plates Saint-Amand Primax

A pair of deep plates made of ironstone from Saint-Amand, Primax model, circa 1930-1940. Night blue decoration on a white background, featuring an elegant frieze of geometric patterns and stylised palmettes with a radiant central rosette. Stamped St Amand, France. Primax model, reference 4017. Diameter 22.5 cm, height 3 cm. In beautiful vintage condition, with a few small patina spots and very slight crazing of the glaze (see photos). Night blue, bright white, bold graphics: the 1930s have lost none of their modernity.
