Ad for Hypnotism Unveiled, or whatever the book's actual title is, by L. A. Harraden. Published in the May, 1899 issue of METROPOLITAN. Perhaps this should be in the Health Quack section, but hypnotism is real and who knows what this books contained. Once you got this free book, Harraden tried to sell on his course of Complete Mail Course of Twenty Lessons in Hypnotism.
