Reproduction of an original pencil sketch of the Sioux village of Kaposia, made June 19, 1851, by F. B. Mayer. The drawing is now in the Edward E. Ayer collection, Newberry Library, Chicago.
Frank Blackwell Mayer, born in Baltimore, Maryland, December 27, 1827; died in 1908. Many of his paintings represented scenes in Indian life, and in 1886 he completed a canvas entitled The Treaty of Traverse des Sioux, the treaty having been signed during the summer of 1851, about the time the sketch of Kaposia was made.
