Why Underdog for the title you may be asking? Oh if only he had both arms in the air, he would match perfectly with the Underdog t-shirt he is wearing....all kidding aside, I believe his name was Captain Pottery. Could be wrong, but I cannot recall what name he was using. He is from the Afton 4th of July parade, which I've posted several photos from during this month of July.
Additional information can be found at Mudslinger Pottery, stop by his website and say hello.
