The St. Louis Amateur Athletic Association (Triple "A") Collection contains photographs documenting the tennis-related activities of the St. Louis Amateur Athletic Association, also known as the Triple "A" Club. Nine loose photographs show the following players: W. Parker, Corinne Gould Chamberlain, Tom Okker, Gus Boehmer, Vernon Tietjen, Ted Eggman, Edmundo Serrano, Ted Drewes, and Fred Josties. Several photographs show African American tennis pro Arthur Ashe. Photographs also show the Triple "A" team that competed in the 1969 Leon Dubler Cup Tennis Tie; players on the Triple "A" Court during a 1961 Davis Cup match; the early clubhouse and courts; and a copy of George W. Parker's Triple "A" membership card. Also included are a photo and article documenting the 1976 fire that destroyed the original clubhouse.

The collection also includes an album with the title embossed on the cover: "Triple "A" Youth Foundation / Annual High School Tennis Tournament." The album contains many snapshots showing players posed on the courts during a variety of cups and tournaments, including competitions for high school athletes. Players are generally not identified. The album also includes letters documenting various activities of the Board of Directors; newspaper clippings documenting games played by a variety of teams and players from St. Louis; and materials related to the construction of the Mallinckrodt Tennis Center. Also included are snapshots showing the opening of new facilities in 1985. Materials in the album generally date from 1956-1990.

Also included are two caption cards and a letter that describes the players listed on one of the cards. The letter references an attached photo, but no photo was attached. It is unclear whether these captions belong to any of the photographs in the collection.
