Wizard of Oz Sculpture

At the rear entrance of the Enfield public library is a very cool 43″ by 27″ by 3″ panel sculpture of a child sitting outside on the ground, holding a book in both hands while reading.
In the field where the child sits, I saw a dozen characters from the Wizard of Oz walking on a curved brick road. I guess we are reading his/​her mind and watching how reading brings imagination to life. The work was a gift from sculptor Janice Loomis to commemorate the 20^th anniversary of the Enfield Library.
You can identify Dorothy, her dog Toto, the Scarecrow, the Tin Man and the Cowardly Lion in the front. In the top left corner is the Wicked Witch of the West riding a broom, the Emerald City, a hot air balloon, and a tornado.
One character I didn’t recognize at all (at least from the movie, since I didn’t read the book) — it was someone with a pumpkin on his head wearing a scarf. I researched the gent and found out his name is «Jack Pumpkinhead» — and he was a character in some of Frank Baum’s fourteen full-​length Oz books.
