The answer: three stripes. Or to be more exact, the as simple as it is recognizable Adidas logo. London based illustrator Marcus Reed used it to create a design theme in a Adidas City Series showing dozens of vintage looking world city icons which all incorporate the three stripes. A2 size prints can be ordered for GBP 40 each here.
I don’t know if Marcus was commissioned to create these or did them on his own, but last week Dezeen published an article about how Adidas aims to use design to increase its market share in America, and a cool looking 3D map of London incorporating the Adidas logo shows up in this posting.
Anyway, the A2-size prints can be ordered for GBP 40 each here.
