'Postcards from America' began in 2010 as an artistic, social and intellectual experiment.  A group of photographers, old colleagues and friends from Magnum, wondered what it would look like if photographers – often the most solitary of practitioners – tried to make something together, to play like a band.  They also wanted to reinvigorate a longstanding artistic tradition of going out into the world that felt challenged by the growing omnipresence of photographs (why travel anywhere to make pictures when someone living there is already doing it?).

These are some of Mark Power's pictures from Milwaukee, part of that project.
