A thought
While at my grandmother's house this thanksgiving, I ran across some strange "Popular Science" books published in the 50s or 60s. They were bound in volumes, like an Encylopedia, and seemed to be very stereotypical of the era in their graphic design. I wonder if it would be worth it, or if there would be any demand if I took some home next time I visit and made some scans, and if so, is there any topics that I should take scans of?
