From the envelope: Harry Keller (1849-1922). Born un Erie, Pennsylvania, Kellar traveled America and made two World Tours with a full evening Magic Show. He was famous or his presentation of Maskelyne's Levitation, the Spirit Cabinet and several automations, including "Psycho." His posters featured little red devils which were copied by other performers. Kellar used many beautiful lithographs advertising his large show. When he retired in 1908 he handed his wand over to Howard Thurston who then became America's foremost magician.
