While these days you may come across bootleg merchandise based off of work by Jean-Michel Basquiat, Banksy, Cost, or Revs in street markets, that used to be where you could find their original work.

Basquiat began selling collages on postcards around the streets of New York City, Banksy sold his work from outside of the London bar, Cargo, and Cost and Revs used to sell their paintings in Tompkins Square Park.
