Scientific American was published by Munn & Co of New York. I have 2 issues from April of 1917 that are complete and in very good condition with just a few minor small edge tears.
Large magazines 10 12 x 15 inches with one having 27 pages and the other 15. Well illustrated magazines and lots of information. Some of the information in these relates to WWI. Includes lots of technical and science related news articles.
