Socialist Realism tall bronze. Mestrovic ?

Tall 59cm (23") bronze sculpture of a working man.
Very interesting Socialist Realism style. Obviously old cast. Circa 1920-1930.

Nice patina. Does not looks like recent edition but more like french 1920's casts.
Marked underneath with ink or with lead pencil "Mestrovic".
Indeed even if I don't have so much info about his sculptures, the bronze could be by Mestrovic.

Anyway a nice, very decorative perdiod art deco bronze.
