I picked up a pile of these gems at the J-Ville community garage sale this summer. I can't believe how much relevant info resides in these pages. Detailed instructions on how to make a mini hot rod boat, DIY speedomoter,etc... Unbelievable. There's even an article about how to preserve food with radiation! Oh the 50's. This is a serious find. Kind of like finding your neighbor's dad's ultimate (and I mean ULTIMATE) stash of Playboys when you were 10. Okay, it wasn't even close to that but it's good.
