Ruby Slippers of Oz

I have dying to read this book for quite some time. I saw a TV show about this book years ago and it had fascinated me. The book is about how the ruby slippers from the Wizard of Oz movie were found 40 years later in a movie studio warehouse. One of the questions discussed is just how many pairs of shoes were found. What happened to them? The man who found the shoes, Kent Warner, led a very interesting life. So many people still covet the ruby slippers. I am just still fascinated how much movie stuff was thrown out by the studios or sold cheaply. Fascinating book and subject.
