Poster - Kellar's wonders - Public domain lithograph

Harry Kellar (1849–1922) was an American magician of the late 19th and early 20th century, famous for his large stage shows during which his head seemed to float apart from his body. He performed tricks such as the “The Levitation of Princess Karnac” and “Self Decapitation”. He was hugely popular in his time, inspiring the likes of Harry Houdini, and reportedly acting as a model for the bald-headed wizard in "The Wonderful Wizard of Oz" published in 1900.
