English: A man wearing top hat, sitting on a dead horse in the street. Picture was taken at South Eighth Street and Indiana Avenue in Sheboygan, Wisconsin between 1876 and 1884 - based on the presence of a bridge over the Sheboygan River in the background and the absence of the railroad tracks that were installed in 1884. http://www.cnn.com/2007/US/01/05/dead.horse.ap/index.html].
Colleen Fitzpatrick determined a number of possible dates for the photograph in The Dead Horse Investigation, Rice University Press, 2008 ISBN 0976716054. In a later blog she further narrowed the most likely dates down to either August 10, 1873 or August 10, 1879.
