Does anyone have information about this pre. 1968 championship. It is not to be confused with the US Professional Championship: http://en.wikipedia.org/wiki/U.S._Pro_Tennis_Championships and also not confused with the the 1968 and beyond US Pro. Indoors held in Philadelphia: http://en.wikipedia.org/wiki/U.S._Pro_Indoor I know that Rod Laver won the event in question in: 1965 & 1967 over Pancho Gonzales both times in the final and Pancho Gonzales beat Rosewall in the 1964 final, at White Plains in New York State. Does anyone have a list of winners/finalists - locations it was played in?
