"In The Style Of Palissy."
Amazing metal work (alloy that I can't determine) of incredible precision. The details are incredibly meticulous. See among others, the scales of the lizards. It is a work in the style of the productions of Bernard Palissy. Late 19th early 20th century. Very heavy and in good condition. Diameter 17.5 cm. A real object of curiosity. Was it a mold? See the photos... Presence of a signature on the edge.
