WWI USMC Marine Corps "DEVIL DOG" Chalkwear Trench Art

Hard to find WWI era USMC Marine Corps mascot Chalkwear. The Bulldog is in rough shape, but he is complete. Front says "DEVIL DOG", right side says: "HE HAS NO MASTER" and the left side says: "U.S. MARINE". Back of figurine has an inscription: "Made by permission of the United States Marine Corps"
He is chipped and nicked and scratched, but even so, he is super hard to find. I saw one of these at a military show 12 years ago with his helmet completely missing its rim, leg glued back on, and spiked helmet war souvenir missing, and the price was $250.00.
This was an Ebay find several years ago for $25.00 He now has a new loving home, and will be taken care of.
Enjoy!
