A schematic transit map displays Chicago's "L" system in clean lines of red, blue, green, and yellow branching across a white ground. The geometric layout captures the railway's network with the clarity of a classic transit diagram, rendered in precise strokes that evoke both functionality and graphic order. Printed on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
