The 1977 Yankees beat the Dodgers in six and even showed great teamwork in autographing this Spalding Official American League baseball (EX). Autographed New York ball highlights a collection including five other team-signed balls from the Orioles, Angels ('76), A's, Royals and Twins. This signature fest averages 29 autographs per ball (EX/8.5) and all are official American League Spalding issue with Larry MacPhail's printed signature. The '77 Pinstripers applying pen between the stitches include the elusive Thurman Munson, Reggie Jackson, Graig Nettles, Mickey Rivers and the rest of the starting lineup, plus pitcher Ron Guidry, reliever Sparky Lyle and, all alone, Billy Martin between the fastball seams. This is a big bone for any autograph hound.
