The collection documents the baseball photography career of George Burke and possibly his assistant, George Brace. The materials date from 1922 to 1951, and the materials include over 7000 acetate negatives, glass-plate negatives, and prints. The majority of the materials are 5 x 7 acetate negatives. These negatives include portraits of various baseball players and managers, including several Hall of Famers like Ted Williams and Babe Ruth. There are also portraits of various American and National League teams, such as the Chicago Cubs and White Sox, Philadelphia Phillies and Athletics, Pittsburgh Pirates, the Boston Bees, Braves and Red Sox, and more. The vast majority of the portraits are taken outdoors in a baseball stadium during practices or games, but some of the photographs are taken in George Burke's studio.
