Some elements of this sign show impressive attention to detail. Note for example the sharp heel, the deft facial profile, and the dynamic leading leg that evokes a pleasant but purposeful stroll by this pictogram-about-town. These careful features lead me to puzzle all the more about his crude claws and anatomically improbable following leg.
Best of all, though, is the incongruence of his choice of direction with respect to the giant authoritative arrow. Is he heedless or contrary, or is he some kind of subversive entity? Or do my eyes deceive me, and is he in fact breezily moonwalking his way away from the danger zone?
There are mysteries everywhere.
