The main item in this collection is a circa 1864 contemporaneous wet-plate collodion glass negative of the original Alexander Gardner wet-plate collodion portrait of Abraham Lincoln taken on Nov. 8, 1863, most likely made by Moses P. Rice, one of Gardner’s studio photographers. Lincoln sat for this photograph just 11 days before delivering the Gettysburg Address. It is one of the best-known photographs of Lincoln and was used by sculptor Daniel Chester French as the model for the Lincoln Memorial in Washington, D.C. The collection includes a modern positive print of the image and the envelope in which IHS received the negative. Collection guide.
