McCandless’ own letters, released for the first time, as well as new and surprising interviews, probe the mystery that still lies at the heart of a story that has become part of the American literary canon and compels so many to this day.

These artists are at the forefront of an expansion of the gig poster genre. MONDO’s reinvigoration of “the film poster as an art form,” and Gallery 1988’s theme based exhibits are only two ways in which this artwork is reaching a greater public. In a community with strong roots, dating back to the 1960s, this expansion is controversial- refreshing to some, sacrilegious to others.
