What Lens Shall I Buy?, Bausch & Lomb Optical Co., (Rochester, NY), 1922, ~4 ½"x7 ½", 48pp
This small booklet describes the uses and models of Bausch & Lomb lenses. While undated in any explicit manner, it bears a code on the title page: "H-al, VI-22, 5M", which probably means it was printed in June of 1922 (the VI-22). On page 20 is shown a photo of the Wrigley Building (tower only), which was completed in April, 1921, consistent with a 1922 printing.
