We have Bob to thank for a heads up to a very cool blog entitled Modern Mechanix.
The blog consists of scans from old technology magazines. It is fascinating what they thought the future would hold. A little taste is the picture below, which shows a mechanical autodialing telephone.
Telephones don't trip your trigger? Then go on over and browse for a bit. Weapons, leisure, electronic devices, automobiles, aviation. Plenty of material for any interest.
