1-7/8" dia. by .5" thick with art repeating on each side. Side in our photo has dent across Buster's face but paint remains Exc. Opposite side has slight raised metal to left of portrait but again paint remains Exc. There is slight paint loss around center rivet and paint off extreme outer rim edges. Seemingly original string is double strand and thus too thick to operate yo-yo as central opening is narrowed due to one dent. Still displays fine with great color. A rare 1930s premium yo-yo.
