It was not until 1995 that the USPS issued a block of 20 first-class letter stamps with the theme “Civil War, 1861-1865, The War Between the States.” The series honors men and women on both sides of the conflict including Confederate General Robert Edward Lee, Union Lt. General Ulysses S. Grant, Union Nurse Clara Barton, and Confederate Nurse Phoebe Yates Levy Pember. Famous places as well as famous faces are part of the historic issue with designs featuring Gettysburg and Shiloh.
