Cullen (b. 1942) played in the majors from 1966 to 1972 for the Senators, White Sox and A's. It's funny that this card has him listed as a Ranger; the Senators became the Rangers after the 1971 season, but Cullen was released by the Rangers in March of 72 and picked up by the A's. He went on to win the World Series with the A's in '72. Also, Cullen was traded by the Senators to the White Sox in February 1968 with Buster Narum and Bob Priddy for Ron Hansen, Dennis Higgins and Steve Jones. He was later traded back to the Senators from the White Sox in August of 1968 for... Ron Hansen. Kind of a weird series of trades.
Cullen had 387 hits, 9 home runs and a .220 batting average. I mailed to Cullen on October 21 and got the card back on October 30, for a 9-day TAT.
