The teaching of play
The Teaching of Play is a 1913 American instructional manual by Wilbur Pardon Bowen, published in Springfield, Massachusetts, for teachers and coaches organizing games and athletics. Its pictures are plain line diagrams: football play schemes with circled player positions, lettered formations, and curved arrows tracing runners, and a basketball court plan with circles and marks for player positions, which a designer could borrow as clean schematic or tactical-diagram motifs.
