Drawing off our common ground, this bespoke piece is an abstract calligraphic depiction of New York City: the skyline, runners, water towers, alleys and more all embedded in a poetic expression of chaos. In the middle of the chaos is a translucent circle – a testament to the melting pot singularity of its citizens and the ultimate embodiment of the place that has been most instrumental to the growth of both himself and Ten Thousand.
