CHICAGO ("chi-COW-go")

Graffiti Tessellation Art by Rossi (Nick Sahli).
Colored pencil and ink on paper.
Notice the bull's head atop the "hic" in the Chicago city name.
The emphasis of one "tile"-- one instance of "Chicago"-- above the others is not part of the original art.
The emphasis was added digitally by Seth Bareiss, webmaster of Tessellations.org
