Today, a sports bar near a professional sports venue is a given. Usually there are many sports bars, and they are loud, boisterous places decorated with photographs of celebrated players and memorabila. Back in the 1890s, one Michael T. McGreevey of Boston opened a bar that became the headquarters of the Boston Royal Rooters, the "rabid and riotous" fans of Boston's various professional baseball teams. His saloon was located near the old Huntington Avenue Grounds, and by the early 1900s, it was decorated with hundreds of photos of baseball players. After his tavern closed in in the early years of Prohibition, McGreevey's collection found its way to the Boston Public Library. This marvelous digital collection brings together more than 170 photographs that once appeared on the walls of his tavern, and they tell the story of Boston's baseball teams and the city's history more generally. Visitors will find images of the old Huntington Avenue Grounds (where the first World Series was played), Cy Young, Boston policemen, and Mr. McGreevey himself. It's quite a collection, and one that is worth sharing with fans of America's pastime.
