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:
"Lincoln was little known nationally until 1858, when he ran as the Republican nominee against Democrat Stephen A. Douglas for a U.S. Senate seat from Illinois. Lincoln gained national exposure during his historic series of debates with Douglas."
