Wizard of Oz Origin (02a) Flipped Compass

Author Michele Rubatino narrates chapter two from her recently published book The Origin of The Wonderful Wizard of Oz. The focus is about the origin of the mysterious maps that Baum claims he discovered rather than penned from his own imagination, that became the famous movie by MGM The Wonderful Wizard of Oz. This published work is derived from research Rubatino has been conducting since 1999 using drafting and computer science skills.
