Griffith Stadium was home to the Senators from 1903 to 1961 and the site of Mickey Mantle's 560-foot homer in '56. Saved from oblivion when the place was razed in 1965, this metal grandstand sign reads "American League Rules" and warns fans not to go on the field during games in black lettering against a white background. 24 x 26" sign is banged up and has holes at the corners, but we bet it will evoke warm summertime memories in D.C.
