Yikes! Busy day, so this is going to have to be another quickie. It's now out of print, but the great Oz artist Dick Martin put out Cut and Make Wizard of Oz Masks in Full Color back in 1982. There still seem to be copies around for sale, so if you're interested you can click on the link above and see about getting these. They're more decorative than practical, but if you're willing to give it a shot you can disguise yourself as one of the major characters from The Wonderful Wizard of Oz, including the Wicked Witch or Toto.
