In honor of Abraham Lincoln's 200th birthday on February 12, 2009, the United States Postal Service issued a series of four stamps featuring the four key roles of his life: rail-splitter, politician, lawyer, and president. You can see all four in this gallery. The artist is Mark Summers.
The official text from the post office that accompanies this stamp reads:
"As President form 1861 to 1865, Lincoln faced the crisis of the Civil War. He preserved the Union, while giving added meaning to the conflict by issuing the Emancipation Proclamation and by calling for a 'new birth of freedom.'"
