Baum began work on a dramatization of his third Oz book, Ozma of Oz (1907), probably in 1908. The project evolved over time; an early version was titled The Rainbow's Daughter, which survives in a detailed synopsis that has been dated to 23 February 1909. This featured Polychrome and the Shaggy Man, characters from the fifth book, The Road to Oz (1909). Another version of the show, preserved in an extant script dated 15 April 1909, is titled Ozma of Oz. Dick Martin and David L. Greene call Baum's Tik-Tok Man "the best of his Oz theatricals."
