Massimo Vignelli's designed this map of the New York subway system in 1972, I personally think it is a stunning and vibrant piece of design which not only informs, it also is eye catching and appealing to look at.
Our influence:
We took influence from Vignelli's design in the form of the line and dot method that he makes use of, the dots representing the stops in the subway.
I particularly love the choice of colours in this map, and think it is the source of the appeal.
