The pictures illustrating this issue were selected through the Prints and Photographs Online Catalog of the Library of Congress, which is accessable to the public at the web address http://www.loc.gov/rr/print/catalog.html. It is my understanding that each of the examples used here are in the public domain, either because their copyright has expired or because they were executed as works for hire for the federal government. It is not my intent to use these photographs in violation of copyright laws. These digital images have been altered by being cropped and by being blurred to diminish the recognizability of individual figures. The mere fact that I have placed an image in proximity to a particular prose work should not be seen as implying a relationship between the individuals pictured and the content, style, or author of the prose work. To the best of my knowledge, no such relationship exists.
