Change Author / Owner : The Human Eye—A Living Camera
Design featuring a multicolored scientific depiction of an eyeball with a diagram demonstrating how the mechanisms of the eye imitate a camera in the upper portion of the composition. A blue eye, with a brown eyebrow, appears in the center of the composition. Two additional illustrated diagrams appear at bottom: one showing how inverted images on the retinas of eyes are brought together to form an upright object and another showing the muscles of the eye that allow the eyes to turn in any direction or converge. The design contains a solid yellow background and explanatory text alongside the illustrations. Printed in black ink, upper left: The human eye—a living camera.
