Stick figures on signs do vary somewhat. They may be squared off -- see next example -- or have rounded ends instead of hands and feet, like this one. He has a protruding rear end, unlike in the USA. The detached circular head is more-or-less universal. One advantage of stylized figures, I suppose, is that no ethnic group can feel slighted when the figure on the sign looks so unlike any real human. Sign is in Dorset, Ontario.
