This 1971 Principia College yearbook is a great keepsake. To use it, simply open the pages to explore the memories and stories. When handling, make sure your hands are clean to avoid soiling the pages. For storage, keep it in a dry and cool place away from direct sunlight to prevent further darkening of the text block. The plastic sleeve on the cover and spine helps protect it, but you can replace it if it gets damaged. Enjoy looking through this wonderful yearbook!
