This peripatetic press was used to print newspapers in the 19th century American West. Washington hand presses were rugged and extremely popular; this one crossed the Isthmus of Panama on its way from New Orleans to California's gold fields. In 1851, the press' owner, John Judson Ames, started San Diego's first newspaper. The press also printed newspapers in San Bernadino; Aurora, NV; and Independence, CA.
