This is probably one of the rarest, a reverse pinstripe ballcap with sewn felt letters. We've only seen one photo of the team in this uniform.\nWe made this hat to the exact specifications of caps from the 1920s, complete with genuine navy wool broadcloth with cream pinstripes and a white felt “AG” emblem. \nIn partnership with the Negro Leagues Baseball Museum (NLBM), we are proud to offer this authentic wool ballcap. A portion of proceeds from this product will support the NLBM in Kansas City.
