The time between the wars – the Great War and WW2 was one of great loss and uncertainty, but also one of invention, creativity and new ideas. The horrors of WWI shattered the belief that progress would continue and reason would prevail. New ideas and patterns of life developed in the 1920′s and in the way that people looked at the world.
The fast pace of technology in the 20′s brought us the lie detector, the traffic signal, bubble gum and Penicillin. An all-electronic moving-image television system somewhat similar to that used today was invented and demonstrated in 1929.
The 30′s were no less invention-intensive bringing us the jet engine, helicopter, tea bags, sticky tape, ballpoint pen and the first photocopier.
However, somewhere between these great world-changing inventions there were some fun and sometimes even hilarious inventions the world has forgotten. I especially like the police revolver with the camera. That should be standard issue today. We’d have a video camera that started recording once the revolver was drawn which would go a long way to exonerating a police officer in the event of a disputed shooting.
It’s a bumper crop of Vintage Danni for your enjoyment.
