"57 steel engravings by various artists, many from photographs. 1 heliographic engraving from a photographic portrait of James W. Gerard. Half-tone by Frederick W. Von Egloffstein's Heliographic Engrav. & Print Co. 135 West 25th St., N.Y. It is interesting that out of 58 portraits only one would be done in a photomechanical process. Breaking new ground was probably not easy: entrenched notions of the proper way to do portrait engravings and possibly the cost prohibition of the new process kept people from trying it." -- Hanson Collection Catalogue, p. 37-38.
