Boston Celtics Logo - Design and History

The Boston Celtics logo is Celtic in gold and black twirling a basketball in a green circle

The world-famous figure has his left eye winking at you, his left hand resting on his shillelagh, his right index finger is pointing straight upward with a brown basketball sitting atop, his left foot crossed over and to the side of the right foot, he possesses a big smile (with a pipe projecting from the right corner of his mouth) and he is dressed in black buckle shoes, black pants, a gold front-button vest with a matching bow tie (with green three-leaf clovers displayed prominently in view on both), a long-sleeved white shirt and all topped off with a black derby hat with the same matching three-leaf clovers.
