Important Inventions of Our Times.

Portable, expanding bridge.

 

Bullet-proof glass.

 

Radio Hat.

 

Electric Heat Vest.

Amphibious Bicycle.

 

All photos are care of The Nationaal Archief of the Netherlands‘ Flickr stream. I’m doing a lot of photographic mining at the moment and, while these aren’t what I was looking for, I needed to show them off!
