Workers labor in a massive industrial factory, their bodies bent over machinery and assembly tasks while massive gears and mechanical forms loom overhead in shades of steel, bronze, and ochre. The composition layers the human figures across multiple levels of the composition, rendered in Rivera's characteristic style with bold outlines, earthy tones, and a narrative focus on labor and human dignity within an imposing mechanical world. Bound with 52 pages of 70lb paper, lined or unlined, behind an anti-scuff matte cover with wraparound artwork, made to order. Notes and sketches kept behind an independent artist's work, not a plain composition cover.
