Below are some bookends sold by the Little Leather Library Co. in special deals or as promotional items. Many of these were crafted by Louis V. Aronson (1869 - 1940). Aronson also created Ronson lighters, inventing the matches used in the trenches of WW1, he was also a master metallurgist. Click any photo below to view larger in another tab.
There are some additional bookends that were possibly used as promotional items as well, but after looking through all the ads, I've been unable to find any connection. These are Praying Hands, Knight, and Longfellow.
