Bausch & Lomb Portrait Lenses, Bausch & Lomb Optical Co. (Rochester, NY), dated 1904, ~6"x9", 24pp
The full title is Bausch & Lomb Portrait Lenses: A Catalog of Lenses for the Professional Photographer. This booklet has great cross-sections of lenses as well as examples of portraits taken with each lens type. It is interesting here to see Bausch & Lomb use the spelling Catalog, whereas prior to this one, all photographic supply companies represented in this collection universally spelled it Catalogue.
