Colton's Map of Philadelphia.

Unbound, colored engraved map, 16" x 13". Slight toning and aging, some finger soiling and staining in margins; overall generally bright and clean and in very good condition. Maps are wrapped with acid free board, or in rigid sleeves. Beginning with J. H. Colton (1800-1893), the Colton family published atlases for over 30 years. Colton's Atlas of the World was first published in 1855 in a large two volume set. In 1857 it became Colton's General Atlas, and Colton's sons, George Woolworth and Charles B. would take over the business. This map of Philadelphia is from the 1857 edition of Colton's General Atlas. The map is very colorful, and provides a lot of detail on the streets of Philadelphia. Extra postage may be required. Ristow 313-326.
