Rare 1970 Boston Red Sox signed road jersey game worn early in the career of veteran pitcher Ken Brett. Gray button-front top is all original with McAuliffe, 70 (year), and 42 (size) tagging stitched at bottom of left front tail. Boston is in individual letters across the chest in navy-on-red felt; same style number 18 is on back. Signed by the southpaw inside the collar (but presenting nicely) in 7/10 black marker. Unknown writing inside tail is in both blue and black marker, presumably a name. Perhaps best known for his association with younger brother and Hall of Famer, George Brett, Ken found a home with no less than 10 different Major League teams in his 14-year career, appearing in 41 games and recording a 4.07 ERA during the 1970 season in which this was worn. Light use shown, in excellent condition. Comes with PSA LOA.
