Trial and imprisonment of Jonathan Walker, at Pensacola, Florida, for aiding slaves to escape from bondage

"1 woodcut from a daguerreotype of Walker's hand inset into title page. 1 steel engraving of Walker, by J. Andrews, both [produced] by Southworth and Hawes Studio, Boston. ... early example of a daguerreotype used to comment journalistically and now seen as graphically striking as well. Southworth and Hawes were later to work enthusiastically with engravers and created a special lens for such work."--Hanson Collection catalog, p. 10
