The original Emidec flowchart template
The shape at bottom left was for printed output, whereas the strange shape at bottom right was a 3D representation of a deck of punched cards!
The later ICT flowchart template
Bendier and more prone to splitting than the Emidec one, but with many more shapes to play with.
Also marked with 10ths of an inch along the top and sixths down the side - for checking printouts.
