Incredible Mexican Muralist painting of David Alfaro Siqueiros reviewing the Miners in Jalisco c 1928.
Siqueiros depicted in the center standing on what would be a reoccurring theme a tuft or outcropping of land His back bent almost broken His right hand shown to be giant holding a lit "bomb" . His left hand holding what appears to be a broken mural painters brush. The crowd looks on as they head to work . The figure in forefront wearing a miners cap and a pick ax over his shoulder.
This seems to be depicting the period after the Mexican government shut down Siqueiros's Murals painters union due to His communist references in His commissioned murals ordered by the government.
The meaning seems to be "you have broken my back/art union but look I'm still strong and powerful see my army of workers "
The painting has no damage no restoration no cleaning , the canvas seems to be late 1930s-late 1940s and is not signed. We believe this may be Siqueiros work due to subject matter and the period of creation. There are similarities in the color pallet (pink army green purple white yellow) as well as the paint used may not be oil but possibly proxylin .
