Did you know?...
The ruby slippers were originally silver, as they were in the L. Frank Baum book. But hey, it's Technicolor and ruby looks better. Speaking of - according to some sources, 7 pairs actually existed. The location of 5 is known. If you're sitting on a missing pair, they're worth about $1.5 million. Source.
As a kid I was taken to the Smithsonian Institute in Washington D.C., and the ONLY things I remember seeing were the Star Spangled Banner and Dorothy's ruby-red slippers. I wonder what that says about me?
