Classic royal blue hat featuring the iconic white embroidered script "B" on front and white button on top. Interior of the hat retains its original Pro KM Cap manufacturer's label along with matching impressed stamp on leather headband with size 7 1/4 indicator. "Robinson" chain stitched in red within the leather headband indicative of attribution to Jackie Robinson. The hat shows light to moderate use throughout. Based on the dating period of the manufacturer's label of 1963-69 we can deduce the likely purpose for Robinson's use was perhaps as a coach/ambassador during Spring Training with the Dodgers as Robinson did participate in same occasionally after his playing career. Interesting and unique Jackie Robinson related Brooklyn Dodgers equipment piece. Includes LOA from MEARS Authentication: EX
