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. Printed on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
