1859                Rooms over Dr. Webb’s Drug and Grocery Store, Cape Vincent, New York.

J. K. Mayo was recorded in one advertisement that ran from September 10 to December 17, 1859 in The Cape-Vincent Gazette (Cape Vincent, New York). War Declared Again. The French have been badly cut up, and the Zouaves, have retreated, to the room over Dr. Webb’s Drugg and Grocery Store, and finally drawn up in line of battle at the Daguerrean Rooms of J. K. Mayo, where every Man, Woman and Child can get just as faithful a copy of their face as they can desire; and at prices to suit the times.  Pictures neatly inserted in Lockets, Pins, Bracelets, &c., with neatness and dispatch.  Rooms opposite the St. Lawrence Hotel.

Mr. Mayo, also gives instruction in Grecian and Oriental Paintings.  Terms reasonable.  Come, see and be satisfied!  Cape Vincent, Aug. 29, 1859.

J. K. Mayo is not recorded in other photographic directories. Craig’s Daguerreian Registry does list a Joseph Mayo as being active in 1859 in Penataquit, Islip, New York. It is possible they are the same person.
