6 x 2 7/8 in. stereoview on cardstock mount (purple and yellow ink/dye residue which may be from later hand coloring, and soiling to print; mount with soiling and significant wear to edges and corners including paper loss to corners). Verso bears printed paper label with series name, image number, caption, and publisher's credit: "Washington City Views., No. 2734, President's Summer House, Washington., Published by E. & H.T. Anthony & Co..." Later pencil inscription also to verso reads "Cheyenne-Kiowa delegation at the White House - March 27, 1863."

Featured here is a delegation of Southern Plains Native Americans including Standing in Water, War Bonnet, and Lean Bear of the Cheyenne (front row), Yellow Wolf of the Kiowa (front row, far right), and several unidentified Native American male and female subjects, posed with their interpreter John Smith. The summit was set in the midst of the Civil War, and the delegation met with President Lincoln, who hoped to not only secure peaceful relations with his guests, but also to persuade them not to join the Confederate forces.  

Within 18 months of the historic meeting, each of the subjects seated in the front row of this photograph were dead. Yellow Wolf died of pneumonia days after this photograph was taken and was buried in Congressional Cemetery. War Bonnet and Standing in Water were killed by the Colorado Territory Militia in the Sand Creek Massacre on 29 November 1864. And Lean Bear, mistaken for a hostile, was killed by the same militia on 16 May 1864, though he protested that he had “visited the home of the white Father.”
