Old science magazine covers…

Flickr member Chainbreaker writes: “I found these old magazines last week at the flea market and thought that the graphics on the covers were great. Some of the articles are interesting but I really enjoy looking through the advertisements and classifieds.” I also really enjoy these old magazines; it’s pretty amazing what people used to make and build. I usually show these at conferences when I talk about about DIY culture and MAKE history. [via] Link.
