How does street art survive in museums?

paraSITE is an artwork by Michael Rakowitz, that consists of a portable shelter for homeless people that has been distributed to over 30 people in several cities in the USA, since 1997, and has been presented in temporary exhibitions since 1999. I use this political work of art to discuss my current understanding of how complex is the (re)presentation of works of art created for the public space at temporary exhibitions in museums of art.
