"History of Early Screws" Folk Art Wall Panel

A chronologically displayed collection of threaded screw-type fasteners ranging from the 18th to the 21st century. This curious history lesson celebrates the wonder of humans' ingenious use of friction to hold many of our man-made products together. A dramatic advance on the security offered by the humble steel nail. 

The Panel is 26 1/2" wide by 19 1/2" tall.
