A souvenir envelope features the 100th anniversary postmark commemorating the 1899 establishment of Silver Spring's post office. Cachet and postmark were designed by Jerry A. McCoy. The 15ยข airmail stamp was first issued in Silver Spring May 3, 1963. Featuring Montgomery Blair, who served as President Abraham Lincoln's postmaster general, the stamp commemorates the international Postal Conference centennial. Initiated by Blair, son of Silver Spring's founder Francis Preston Blair, the I.P.C. established uniform mail rates and weights between nations. |
