The famous "The Wicked Witch" candle wax 3D relief artwork by an anonymous artist, hangs in the Emerald City Museum Of Life And Science, courtesy of the Giggleheim trust. The piece is considered to be at least a few minutes old, and therefore is considered priceless by Oz's top Museum Directors as evidenced by their high shaking heads. "It's a dangerous type of art," says local curator, Ric Ocasek.
