the traffic signs of the world site collects pictures of three warning signs from around the world. the featured signs are “children crossing”, “falling rocks” and “men working”. i particularly like the commentary on the british “children crossing” sign that notes that in childhood the girl is dragging the boy across the road but in our superannuated “elderly people crossing” sign the woman is pushing the man onto the road. it’s odd what you never notice in the things that you see every day.
