The Cowardly Lion
The Tin Man
(He's supposed to be a scarecrow. I think the hat looks more like a Sombrero)
The Wicked Witch of the West
Toto (a very sleepy Toto)
Glenda the Good Witch
I saved the best for last: Ringo's Tin Man costume!
* Once again, I must give Karin over at Flickr credit for this because her creativity is what gave us the idea for these costumes! Thanks, Karin!
