DALLAS (March 14, 2014) A rare, 165-year-old map of Texas that has been in the same family for generations is expected to sell for more than $150,000 at auction this weekend.
The 1849 first edition map, considered the first official map of Texas after it became a state in 1845, will be offered Saturday in Dallas by Heritage Auctions.
The map was one of several historical family items that Patrick Martin, 66, a retired architect, decided to bring to an appraisal event Heritage was holding last spring in Birmingham, Ala., near his home.
Joe Fay, Heritage's manager of rare books, called it a "eureka" moment when he realized the map was a first edition.
Fay said the map, a lithograph, was hand signed by Jacob De Cordova, a land agent who commissioned the map.
