The Triple Mystery Cube was first created by Carl Brema c. 1932 with a brass cube. His son, William Brema, continued to make a high-quality version in plastic during and after the Second World War for Kanter’s and others called Cubio.
This is a great fooler that can be set and cleared in front of the spectator, and it wasn’t until 1964 when Tenyo started selling their version which is probably what most people will remember.
