Milbourne (b. 1951) played in the majors from 1974 to 1984 for the Astros, Mariners, Yankees, Twins, Indians and Phillies. He had 623 hits, 11 home runs and a .254 batting average.
I mailed to Milbourne on February 28 and got the cards back on March 21, for a 21-day TAT. I paid a fee of $5.00/card.
