At the lower left of the sheet, a faint head of an old man emerges in delicate profile, his features rendered with subtle, curving lines that suggest a thoughtful expression. Just above this head, a few lighter, almost ghostly outlines hint at other facial studies, barely visible but present in the textured surface of the paper. The upper half of the sheet is filled with mechanical studies drawn in brown ink, including a large, complex device at the upper right, composed of cylinders, levers, and a slanted chute, all arranged with careful attention to structure and function.

Below this, a cylindrical object with a protruding handle is depicted, its form clearly defined by straight, confident strokes. Across the top and left edge of the page, lines of compact, right-to-left mirror writing run horizontally, their brown ink matching the mechanical diagrams, and their presence suggesting notes or explanations related to the inventions sketched below. Scattered brown spots and patches of discoloration mark the paper, bearing witness to the age of the sheet and the passage of time since its creation.

Fine, controlled hatching is visible in the old man's face, while the machinery is described in more schematic, linear terms, and the swirling mass below is rendered with rapid, overlapping lines that suggest movement and texture. The background of the sheet is a warm, creamy beige, mottled with irregular brown stains and darker patches, especially along the left and lower edges. The upper right corner is relatively clear of marks, with only a few faint smudges and the edge of the mechanical drawing intruding into the space. Head of an Old Man, and Studies of Machinery is by Leonardo da Vinci, whose name appears in the title line for this sheet.
