Kansas City: Ackerman-Quigley Litho Co., ca. 1905. Oversize three-sheet medallion bust portrait lithographed poster of the American hypnotist who worked together with his wife and daughter. 40 x 80". Significant over-coloring and restoration throughout; B. Scarce. Once considered the preeminent hypnotist in America, Flint took no chances when it came to his performances. By one report, at the height of his career, he carried as many as twenty “horses” – stooges, paid to act as if hypnotized, but apparently just audience volunteers – with his show. For a time, both his daughter and second wife, Grace Marion, worked together with Flint on stage. An avaricious and brutal man, he was known as much for his temper as he was for his abilities as an entertainer. Flint retired to Cleveland, Ohio where he published and sold mail-order courses on hypnotism.
