An 1859 map of the Michigan counties of Genesee and Shiawassee in the possession of the Swartz Creek Area Historical Society is falling apart, and the society is wondering whether it’s worth spending the $3,000 to $5,000 it will cost to restore it, the Flint Journal reports: “‘I really don’t think it’s worth it for that kind of money,’ said Bill Morgan, founder and president of the historical society.” The map sat in an attic for decades; it’s unclear how many copies of it remain, though Morgan is aware of one other, plus a copy. (On MapHist, whence the link to this comes, there is a report that the Library of Congress has two “pristine” copies.)
