The Wizard of Oz (1902 musical)
The Wizard of Oz was a 1902 musical extravaganza based on "The Wonderful Wizard of Oz" by L. Frank Baum, which was originally published in 1900. Much of the original music was by Paul Tietjens and has been mostly forgotten, although it was still well-remembered and in discussion at MGM in 1939 when the classic film version of the story was made. Although Baum is the credited bookwriter, Glen MacDonough was hired on as jokewriter after Baum had finished the script.
Little Wizard Stories of Oz
Four of the "Little Wizard Stories" were re-issued in 1932 in a new form, as "The Little Oz Books with Jig Saw Oz Puzzles". A year or two later the four tales were released again, as part of a promotion for a "Wizard of Oz" radio program (sponsored by Jell-O). Rand McNally published the six stories in three booklets in 1939.
