Rare real-photo postcard capturing a Boston Red Sox game in progress at the Huntington Avenue Grounds. The photo, taken from the perspective of the grandstand behind first base, captures the entire infield. The Red Sox are in the field and the opposing team has runners on second and third, with the batter having just swung at a pitch. The Huntington Avenue Grounds was home to the Red Sox from 1901 to 1911. Despite the lack of a listed year, the AZO stamp box on the reverse dates to the 1904 to 1918 manufacturing period, which indicates that this image can be more narrowly dated to the eight-year period 1904 to 1911. Regardless of its exact year of origin, it remains an outstanding and rare Red Sox image dating from the earliest days in franchise history. The postcard (5.5 x 3.25 inches), has been neither addressed nor mailed, but there are a few pencil notations on the reverse that include "Huntington Av Grounds, Boston" and "1903-1911 Fenway 1912." A small diagonal crease is evident in the upper right corner. In Very Good to Excellent condition overall. Reserve $200. Estimate (open).
