"Two maps in one folder, as issued; brown cloth covers 13.5x8.5 stamped with grape-design has ""Burr's Map Of The State Of Ohio Published By J.H. Colton & Co. New York"" printed in gilt. The full color Burr Ohio map is engraved and printed by S.Stiles & Co. The uncolored Portsmouth map is lithographed by P. Desobry's, N.Y.C. The first edition of the Ohio map was issued in 1833. Inset of Cincinnati. One of Colton's early maps and one of several he published with Burr. The map of Portsmouth appears in no records but seems similar to several maps issued in 1833 to show the opening of the Ohio & Erie Canal. There is a view on the map of ""Proposed Front of One Block"" which shows buildings to be erected, so this may be a promotional real estate map, as well."
