Inavi Italian theater antique powder dispenser, 1940s

Theater powder dispenser from the 1940s - Italian Fascism era, deducible from the shape and from the letters that make up the INAVI writing on the top, which is probably the brand of the object. The powder box is in stained walnut wood with aluminum lettering, and on the back it has 4 bakelite knobs that were used to raise the level of the powder contained.
The remains of the cosmetics are still present in the 4 containers.
A real museum piece.
