An original engraved map, titled "A Map of the Genesee Lands in the County of Ontario and State of New York according to an accurate survey which was made of the same 1790", printed in the year 1849 by engraver Richard H. Pease of Albany (1813-1869; his name at extreme bottom). The map shows Lake Ontario at top and the Finger Lakes region from Canandaigua Lake at the far right to generally the Genesee River at left. There are charming details such as "Village", "Settlement", "Saw Mill", "Grist Mill". Included at lower left within "Explanation" is "In 1789 and 1790 the settlers on the different townships amounted to 1047 persons" and "The Spurs of the Alleghany Mountains run in upon the three first ranges, the Lands exhibit hill & dale with rich bottoms & may be cultivated to the tops of the rising grounds". All in all a charming old map of the region. Being old it has acquired some faults, including a torn missing area at extreme upper left corner, and there is old browned tape residue at left center as seen. Within the margins, a small missing area at upper right and there is some writing at lower left margin, on the back side, which shows through. Properly matted the map remains very collectable and interesting. Measures 13 1/2" by 9" (16 3/4" by 13" as simply protectively framed).
