Cake plates lantern KG Lunéville

Set of 4 cake plates from the Réverbère collection by the Lunéville factory. Unique and handcrafted pieces in faience, made in Lorraine and signed by K.G. (Keller and Guérin). From the late 19th century, they have been in my family for a very long time. They were hung on a wall, so very little used, but one has been cracked (see photo). Diameter: 21.5 cm. Currently sold on Vessière Cristaux for €55. No delivery possible, hand delivery only.
