Before swimming pools had lane ropes and digital timing systems, they had picture-lessons — sequential diagrams printed in educational encyclopaedias, showing the body in motion through water with the calm authority of mid-century instructional design. Both covers reproduce the Four Picture-Lessons in Swimming and Diving from the Book of Knowledge educational series (Grolier Society, 1940s–1950s): the crawl, breast stroke, side stroke, and swallow dive in sequential diagrammatic form, rendered in the clean, confident graphic style of postwar educational illustration, with figures shown in profile against neutral backgrounds to isolate technique and body position.
