The George F. Jowett Progressive Power Method for Attaining Your Muscular He-Man Build (Lessons 1-12, complete)

First lesson housed in a printed wrapper, bound with brads that could be used to swap out the content of each lesson. Lessons 2-12 housed in a binder with 2 printed "He-Man" related booklets promoting the Jowett Institute of Physical Training: "How to Achieve Nerves of Steel, Muscles like Iron" (28 unnumbered pages, dated 1951) and "How to Mold Yourself into A Mighty Man" (32pp, a sampler of 5 longer works in the series, no date, ca. 1952). The lessons contain photo-illustrated leaves showing each exercise at the end of each lesson. Lessons about Very Good with light foxing and edgewear; booklets Near Fine. The course content bears a 1927 copyright "Jowett Institute of Physical Culture," but was used by a budding bodybuilder in 1952, with his date and lesson numbers penciled on the first page of each installment, else unmarked.

George F. Jowett was one of the first to apply the correspondence course method of education to physical training. He adopted a personal tone that made the learner feel like part of the "club," a proven tactic for popular fitness guides to this day. "Dear Friend and Body Builder: Here we are again. Full of life. I have just gotten through taking a little extra work-out as I have been confined too closely of late... I feel like a race horse. Rarin' to go." An uncommon example of the complete correspondence course and with later materials reflecting the evolution of fitness as pop culture—consider the photographs illustrating exercises in the 1927 guide versus the glamorous booklets, and even the branding shift.
