The Lexington Concord Commemoratives were the first of many commemoratives issued to honor the 150th anniversary of  events that surrounded America's War of Independence. Many of these commemoratives are what we now call the "2¢ reds". 

Strangely, not all the stamps in this set honor the famous Battle (or rather series of skirmishes) at Lexington and Concord. The one cent stamp depicts Washington assuming command of the American troops at Cambridge a full two months after the skirmishes. This is even more amazing in the fact that the skirmishes were immediately preceded by one of the most famous events in American history, namely the "midnight" ride of Paul Revere from Boston to Lexington and Concord. A congressman from Cambridge, Massachusetts convinced the Post Office Department  that there was a link between Washington assuming command in Cambridge and the Lexington Concord "battle". Most would agree that a stamp depicting the ride of Paul Revere would have been more appropriate, but politics prevailed.

The two cent  and five cent stamps honored both Lexington and Concord; the two cent the actual battle at Lexington and the five cent the "Minute Man" statue at Concord.

All three stamps were placed on sale at the Philatelic Agency in Washington, D.C. and five Massachusetts cities that were an integral part of the Lexington Concord story: Lexington and Concord of course, as well as Boston, Cambridge, and Concord Junction. First Day covers are known from all six cities. The 5¢ stamp has a line over head variety listed in Scott.
