[Heliographic engravings in Atlas of New York and vicinity]

Beers, F. W. (Frederick W.). Atlas of New York and vicinity, from actual surveys · 1867

"5 Plates with 14 engravings, 12 illustrations from art and 2 from photographs...These plates were created by Frederick W. von Egloffstein's Heliographic Eng. Co., 135 West 25th St., N.Y. George Rockwood, N.Y., is credited as the photographer on the two photographs. These are the largest plates by von Egloffstein commonly found. They represent the peak of his business, which lasted apparently only two years. Very few publications exist with this special half-tone method. This collection has most of the representative plates currently known to exist."--Hanson Collection catalog, p. 31
