Framed vintage orchestra poster

Rare painting late 19th - displays the hungarian ladies of the grevin museum. It represents a female orchestra and their conductor. The illustration is signed jules chéret for the chaix printing house. We see a small stamp and a signature on the poster, visible in one of the photos. I do not know if it is a real (found in flea markets formerly) The frame is original, made of wood, and has various defects related to natural wear: visible splinters. It is 32 cm wide and 43 cm high.
