Prof. L.A. Harraden's complete mail course of twenty illustrated lessons in hypnotism
A correspondence course in hypnotism published in Jackson, Michigan, in 1899 by L. A. Harraden, aimed at mail-order students wanting to learn stage and parlour suggestion. Its pictures are loose pen-and-ink figures of men seated or standing in demonstration poses, with short captions describing each suggested state, such as a man reciting a story or believing he is tarred and feathered. A designer could draw on their hatched shading, expressive gestures, and the plain, instructional layout of late-nineteenth-century mail-course pages.
