This is a black-and-white drawing of a human heart. It’s cut open to show the inside chambers and blood vessels. The outer surface has a textured look, like raised veins, while the inside is smooth with a dotted line marking one section. The artist labeled it “Wetselaar,” which might be their name. The drawing is precise, focusing on how the heart’s parts fit together. Look up cross-hatching to see how artists create shading with lines.
