Historic wooden City of Boston key made from an elm tree which stood on the Lexington Green battleground when the first shots of the American Revolution were fired on April 19, 1775. The key measures 10.5 x 3.5 x .5 and bears affixed brass plates to front and back affirming that the key commemorates the Tercentenary of the Massachusetts Bay settlement in 1930 and that it was presented by Boston Mayor James Michael Curley. The key is housed in a velvet-lined mahogany display box, 12 x 4.5 x 1.75, with an engraved plaque affixed to top. Includes a scarce circa 1936 gold-washed bronze medallion commemorating Curley as Boston governor, measuring 3″ in diameter, designed by John F. Paramino and struck by the Medallic Art Co. In fine condition. Accompanied by a copy of an extract from an article of The Lewiston Daily Sun from March 20, 1931, noting that Curley presented the key to D. J. McGillicuddy of Lewiston, Maine.
