W. Calhoun Cralle was recorded in an advertisement that ran from May 4 to June 7, 1854 in The Daily Dispatch (Richmond, Virginia). New Skylight Daguerrean Gallery—W. Calhoun Cralle, Daguerreotypist, having opened Daguerrean Rooms in this city, offers his professional services to the citizens and public generally. He will give his constant personal attention to his rooms, and hopes by strict application to business to be able to execute Pictures in a style worthy of the art and its professors; yet he will make no promises to excel, but submits his claims to patronage to a discriminating public on his merits. He can be found at his Rooms, No. 37 (Mansion House) Main street, from sunrise to sunset. Pictures taken in any kind of weather. Prices uniform.
