Nature Magazine - many old issues

I had never seen this magazine before i bought two large boxes of old issues at a flea market in Santa Cruz about 7-8 yrs ago. They range from the 1920s thru the 50s and a couple in the 60s. Although some of the stories are a bit corny and dated, most of them are based in good science of the times and are very interesting. The magazine was produced by the American Nature Association in Washington DC.
