The Mentor (Bookshelf)

The Mentor started as a weekly in 1913, but changed to twice a month already in its second year. Each issue covered one topic, and were accompanied by six loose plates of "exquisite intaglio gravures". The fact that these were loose pages rather than bound, makes complete issues difficult to find.
