I'm guessing that the ball was signed in 1971-72, probably in Detroit.
The 1971 AS Game was in Detroit, so all those players, including national leaguers like Millan, would have been there together.
Duke Sims was with the Tigers in 1972-73.
Willie Horton was a Tiger from 1963-1976.
George Mitterwald was with the Twins from 1968-73.
Carlos May was with the White Sox from 1968-76
Ed Spiezio was a career national leaguer, spending only 1972 in the AL with the White Sox.
So the unknown signature would have possibly been a Tiger, White Sock or Twin, probably in 1972, if he wasn't a 1971 All-Star.
