Are they sure those were the ones actually worn by Judy?
The legend is the studio had 4 pairs made in case one pair was ruined,
according to Rhys Thomas, author of “The Ruby Slippers of Oz,” a book about their history.
Yes, there was more than one pair of the ruby slippers.
One pair was specifically made for close-up scenes, from what I heard.
The real Legend is my dad grew up in Culver City down the street from MGM he and his buddy’s loved to tease the muchkins going in and out of the studio
