Stewart collection of Abraham Lincoln material comprises artifacts, prints, postcards, stamps, coins, clippings, publications, notes and research, and an 1861 appointment signed by Lincoln. The collection documents the nation’s mourning of Lincoln through contemporary and commemorative ephemera, artifacts, and prints and reflects the collecting and research pursuits of native Delawarean, University of Delaware alumnus, and DuPont executive Richard H.
