Vintage solid brass tray

Solid brass tray and its six coasters from the 70s (2, 4kg!) grass engravings in the center. Signature on the back to be determined, according to my research, this object is to be determined. Beautiful decorative object with a nuanced patina... Some micro-scratches and traces of oxidation. Diameter of the coasters 10 cm. I try to describe in all the best and honesty the peculiarities (negative or positive) of this object, however do not hesitate to contact me if you wish for further clarification or photos that I could have oised; I would be happy to respond as soon as possible.
