"Tell pitiful story" (Hoboglyphs)

I’ve been thinking lately about the notion of

codes in plain sight

…and today I’m especially enchanted with hoboglyphs, used in the 1920s to allow hobos to secretly communicate with each other. What messages do we overlook, walk over, drive past each day, unrecognized? Who is using public spaces to share information? What are they sharing, and to what end?


Portal 11. Intercepted communique; author(s) unknown; meaning(s) undetermined; outcome(s) unrecorded.
