Please email with any questions. POPULAR SCIENCE MONTHLY magazine, lot of thirty issues from 1949 through 1956. Most of the condition issues are with the covers which have varying degrees of wear. a couple are missing the back covers, also 1 or 2 covers are loose, spine coverings are worn or missing. Binding in these issues seems pretty good and the texts seem to be quite clean. Since this was the Post War/Cold War era you will find a lot of articles that relate to the general mindset including how to build your own "shelter" in case of attack. There are also many articles that look to the future with optimism- new inventions, television, futurism, how to make money schemes etc. Lots of fun to read even if you don't like science or aren't very popular.
