Popular Science Magazines

Popular Science from the 1940s to 1970s or thereabouts. Most are in good condition. Some with front or back cover torn or missing and some with sellotape repairs but most are fine. Some repeats. I counted 1 lot of 27 so approximately 160 magazines. At $5 each that is $800 but some are worth $50 or more - especially the space travel and jet aeroplane ones from what I see on Ebay. They are heavy so pickup only really but you are welcome to ask. I cannot get a quote on shipping but would expect over $100 at a guess.
