Superman Hobo Signs

In the current Superman comics written by J. Michael Straczynski and Eddy Barrows, Kalel is walking across the US, earning meals by performing chores and helping people. Perhaps, like homeless wanderers of old, he might leave Hobo Signs -- etched symbols that communicate information useful to fellow travelers. So humorist Chris Sims contemplated what signs Superman would leave for other metahuman hobos.
