In May 2011, Magnum photographers Jim Goldberg, Susan Meiselas, Paolo Pellegrin, Alec Soth and Mikhael Subotzky, as well as writer Ginger Strand, set out from Austin, Texas in an RV. Two weeks and 1750 miles later, they arrived in Oakland, Calif.

Together, they documented their experience, the result of which is a new, limited edition book that launches this week. Postcards from America is a collection of objects: a book, five bumper stickers, a newspaper, two fold-outs, three cards, a poster and five zines, all in a signed and numbered box.

“We knew each other through Magnum, obviously, but we’d never actually tried to work together,” says Soth. “We wanted to see what that would be like, to see if we could create a kind of polyphonic sound. Hopefully the box book achieves that. It also gave us an opportunity to push each other creatively and conceptually, which I think has carried over into our individual work.”

The book does not attempt to document the American Southwest in a traditional sense. Instead, it uses the prototypically western experience of a road trip as an entry point into depicting the region. “Some of us are used to working only on immersive, multiyear projects,” says Subotzky. “Obviously this was very different. Doing it collectively brought a great energy and looseness to the work. The box, with all its moving and arrangeable pieces, really reflects that and reflects what we found on the road—a divided and often contradictory society, unsure about its identity and future.”

The Postcards from America box book, in a signed edition of 500, is available exclusively at www.postcards.magnumphotos.com

The second Postcards from America project is scheduled to begin this April in Rochester, New York.
