Inventions, patents, and more... From the early 1900's...
Item # 180068 SCIENTIFIC AMERICAN SUPPLEMENT, New York A lot of ten issues from 1900 - 1915. Not a "supplement" of the regular issue, but rather a separate stand-alone title which got its start to report on the Centennial Exposition in Philadelphia. Nice condition with a wealth of illustrations and photos throughout.
