Frank Robinson was inducted into the Hall of Fame in 1982. New Era manufactured size "7 1-2" cap with the manager number "20" handwritten under the bill in black marker. An Orioles team logo is on the front and sweat staining is present. Robinson signed the bill of the cap in black marker and in our opinion rates a 9. This cap is properly tagged, was presented to us as manager worn and shows use. Accompanied by an ALOA from JSA.
