Mental and physical ease and supremacy;
A 1914 Chicago book by C. Franklin Leavitt, titled Mental and physical ease and supremacy, filed under mental healing and mental health, and apparently aimed at readers seeking self-improvement through exercise. Its photographs show a shirtless man in a singlet and track trousers performing standing postures and stretches in plain studio settings, in grey monochrome halftone; a designer might take from them the clean, instructional way mid-century exercise photography isolates body positions against a blank backdrop.
