This huge-sized "Think Big!" tennis racket, model MG-767, dates from the 1970s and is big enough for a giant to use. Black painted wood form with white and red accent stripes, strung with white nylon string. Reads "100% Graphite Fibres," it measures 54" long and is NRMT. Think Big! was a classic NYC store - now defunct - that sold big everything, from Chinese food take-out containers to a Babe Ruth bat.
