Collection of three vintage real-photo postcards capturing World Series action. Unless otherwise noted, none of the cards has been addressed or mailed. 1) Game-in-progress scene from Game 2 of the 1916 World Series between the Brooklyn Robins and Boston Red Sox at Ebbetts Field (this was the first game at Ebbets Field in the Series). Taken from the perspective of the left-field stands. The postcard features neatly printed handwritten notations in black fountain pen on the front, including identification of the Red Sox players in the field, the inning (bottom of the first), the date (October 10, 1916) and the final score (Brooklyn 4 Boston 3). Addressed in pencil on the reverse but not mailed. Vg. 2) Photo of the fans in the outfield stands during the 1920 World Series. The white-printed caption on the front reads "Part of the crowd of fans who saw Cleveland win the World Series from Brooklyn 1920." Vg. 3) Game action at the Polo Grounds. The year is unknown. A typed caption along the base reads "World's Series Base Ball at New York City Polo Grounds." The photographer's credit, which is only partially legible, appears in the lower right corner. Vg-Ex. Total: 3 postcards. Reserve $100. Estimate (open).
