Round hollow dish Art Deco stencil decoration

Pretty old dish, with a harmonious shape in flared cut and a simple and graphic decoration, made with stencil, which recalls the codes of art deco, in blue and red on the background of ecru color. It can be used as a fruit cup, a dish to present some dried fruits at the aperitif or as a pocket empty... There is a marking below, in hollow: a capital "p" followed by the symbol of pi (mathematical), and a printed marking: the number "32", but no other indication, so I could not identify the earthenware... Maybe an investigation to conduct, and to give a small lead, this dish was part of a full service (of which 4 plates are on sale here, in batch, in my shop), and I found it in lorraine... Sarreguemines digoin. Lunéville. Niderviller. Perhaps a "reformed" piece (indeed, the stencil decorations have some imperfections), and therefore not officially stamped, then sold cheaper, out of manufacture, to the locals... I know it was done at the faience factory in niderviller, so it's likely that other factories did it... It is in good condition, neither cracked nor shiny, but does not hide its age: the enamelling begins to present some cracks, some small spots, scratches and abrasion marks, but all not very visible. It measures 25 cm in diameter and 4.5 cm in height, and weighs just under 500g.
