In April 1925 the United States Post Office issued three stamps commemorating the 150th anniversary of the Battles at Lexington and Concord.
The Lexington—Concord commemorative stamps were the first of many commemoratives issued to honor the 150th anniversaries of events that surrounded America's War of Independence.
The three stamps were first placed on sale in Washington, D.C. and in five Massachusetts cities and towns that played major roles in the Lexington and Concord story: Lexington, Concord, Boston, Cambridge, and Concord Junction (as West Concord was then known).
This is not to say that other locations were not involved in the battles.

The events were also commemorated on the 1925 Lexington-Concord Sesquicentennial half dollar.
