There flows from Latin America

The composition is highly narrative, featuring a central industrial scene (train, factory) juxtaposed with text blocks that convey a strong political and economic message. The use of a horizontal layout guides the eye from the source (Latin America) to the destination (USA), emphasizing the flow of resources and labor.

The image combines illustration (the train and factory) with dense, block-text typography, typical of propaganda or public service announcements from the early 20th century. The drawing style is detailed and somewhat didactic.
