有声读物: Mentor 2

The Mentor Association was established to increase interest and knowledge among the public in the areas of art, literature, science, nature, history and travel. The association published a magazine twice monthly, each dealing with a different topic and often written by a recognized authority of the day. They were easy to read, visually appealing and affordable. This collection includes selections from issues dating from 1913-1919. - Summary by Lynne Thompson
