Most of the Men at Work signs (
†) which have been reported
 from Iran, are similar, sometimes identical, to the roadsign found in 
Great Britain.
 Because, by convention, a man should work with his back turned to the trafic, the UK-original is not
 adapted to Iranian trafic. They must have realised this as many mirrored signs can be seen along Iran's roads.
The drawing comes in many slight variations. The head may be
 a circle, or more realistic. A neck may be present, or not. The drawing may fill the canvas, or only the center.
 On a rare occasion, text may be included. The spade may enter the heap near the top, in the middle, or almost at
 the bottom. And the face of the heap can very widely. Things which make sign spotting in Iran
 very entertaining.

†: The same holds true for the other roadsigns as well.
The collection of warning signs (Men at Work, Children's Crossing, and Falling Rock Signs)
 all following the layout found in Great Britain, is called the UK-group of signs.
 It is a good tool to trace historical connections between countries.
