New York Philharmonic/Subway by Djamika Smith
Submitted by Benjamin, who says: It’s a few years old, but this New York Philharmonic poster by Djamika Smith is pretty cool. Transit Maps says: A fun idea, nicely executed. I particularly like that the route lines appear to be labelled as “A” through “G”: the notes of a musical scale. Source: Djamika Smith’s website – link no longer active
