8 old plates Sarreguemines cubist décor

Rare set of vintage antique plates. Manufacture sarreguemines. Model le mexciq jazz series. Post-cubist décor. Probably 40s. 8 flat plates. Diameter about 24 cm. Neither crack nor shine. Except a small discreet shine on the back on the foot of a plate (very discreet see photos) 1 brown spot which is a small manufacturing defect. Gilding very slightly passed in places. Surprisingly well preserved. Small lack of color in the decor due to manufacturing. Seem to have served very little...
