This stamp salutes Abraham Lincoln’s Postmaster General. Blair served from 1861-64. He called the first International Postal Conference at Paris in 1863, and it became the forerunner of the Universal Postal Union. Blair also put into effect George B. Armstrong’s idea of a Railway Mail Service in 1862 and a Postal Money Order System in 1864.
