This is one of two Foster presses known to exist. This particular press was used to print the Weekly Jeffersonian Newspaper in Findlay, Ohio during the Civil War. The paper attracted national attention when its publisher, David R. Locke, wrote a series of satirical letters under the pseudonym "Petroleum Vesuvius Nasby." In the "Nasby Letters," as they became known, Locke used the character of a Confederate sympathizer to encourage support of the Union cause. George S. Boutwell, U.S. Secretary of the Treasury during the Civil War, credited the Union's success to "the Army, the Navy, and the Nasby Letters."
