This vertical propaganda poster features a central illustration of a young man with dark, wavy hair and a light blue collared shirt with rolled-up sleeves. He is shown from the waist up, holding a wooden pole that supports a large Mexican flag—a tricolor of green, white, and red with a central eagle emblem—which billows behind him against a sky of grey and white clouds. In the distant background behind the man's right arm, two dark silhouettes of ships are visible on a body of water. Across the lower half of the poster, the Spanish text "EL GRITO DE GUERRA" is written in large, three-dimensional yellow block letters with red outlines, tilted at an upward angle. Small, faint text is visible at the very bottom edge of the image, and a vertical color calibration strip is positioned along the right side of the poster's border.
