This Popular Science magazine from 1942 is a great collectible. To use it, simply sit back and flip through the pages to enjoy the historical content about new torpedo warplanes. When handling, be gentle due to the fragile binding. Store it in a dry and cool place to prevent further soiling or damage. Avoid bending the spine too much to prevent more loss of material. If you want to clean it, use a soft, dry cloth for the covers and pages, but be very careful not to cause any tears.
