While commemoratives had honored Civil War figures and events in such stamp issues as the Army Navy 1937 series and the Centennial celebration of 1961–1965, comprehensive coverage of the conflict did not appear until 1995, when U.S. Postal Service issued its most ambitious commemorative of the Civil War to date in photogravure sheets of 120 in six panes of 20. The four events pictured were Battle of Hampton Roads between the "Monitor" and "Merrimac" ("Virginia"), Battle of Shiloh, Battle of Chancellorsville and Battle of Gettysburg. Presidents included Jefferson Davis and Abraham Lincoln. Union officers included Ulysses S. Grant, David Farragut, Winfield Hancock, and William T. Sherman. Confederate officers included Robert E. Lee, Raphael Semmes, Stand Watie, Joseph E. Johnston and "Stonewall" Jackson. Civilians included Clara Barton, Frederick Douglass, Harriet Tubman, Mary Chestnut, and Phoebe Pember.
