i am not positivily sure but i know no one in Baseball wears #42 and that the number is in every ballpark as a giant decal or sign. #42 was the number Jackie Robinson wore for the Brooklyn dodgers and that he was the first negro to play baseball professionly in America. now there were negro leagues but they were not considered major league. so i know for a fact that no one in mlbwears it and possibly football and basket ball also

Doug Kotar wore number 44 for the Giants
21 for the yankees because they wouldn't let him wear 44 (reggie jackson's #). 44 for the white sox.
Requires professional appraisal.
Jackie Robinson was number 42...
Hank Aaron wore uniform number 5 during his first year with the Braves in 1954, and wore uniform number 44 the rest of his carrer, 1955 -1976.
