earthenware egg or snail display from the 1950s

Curious ceramic display from the 50s/60s. Stunning brilliant toned colors. This is an egg display with egg cups or a large snail casserole dish. Composed of a small pot with 2 handles, a black plate with holes and 6 egg cups. The whole thing is in excellent condition, without any accidents. I think, however, that 4 egg cups are not original but are brought back. Presence of a signature underneath to identify. Very original and fun piece. Height without egg cup: 8 cm width with handles: 27 cm diameter without handles: 20.5 cm egg cup diameters: 4.3 and 4.6 cm total weight: 1210 gr, 20623/7.
