Maryland & Delaware states 1855 Cowperthwait map county slave population shown Geology Economic values by county areA New Map of Maryland and Delaware with their canals, roads & distances. Published 1850 55, Phila. by Thomas, Cowperthwait & Co. (This variant issue likely being 1854 5 despite the imprint at bottom stating 1850). There are several variants of this map which all display the same 1850 imprint but were released across years within atlases having later title page dates. Fascinating mid 19th century (engraved) lithographed map with original hand color.
