My love for 60s and 70s rock and roll music is what made me think about the design. 500.000 people getting along, even without authority, seemed something to think about. I actually went to visit the original site and took this photo when i was in New York on vacation. The design was inspired by the Canned Heat song Remember Woodstock. The lettering itself is something inspired on festival posters from that era.
As usual I started drawing on paper in my notebook. After having the idea on paper, I photographed it and loosely traced it digitally. Eventually I printed the shirt to wear it myself.
