Accordions bearing stories

This looks pretty great: New-York Ghost contributor Ben Greenman's Correspondences. And...complicated:

But the literal subject of the work is only the beginning of the discussion: Each hand-crafted, signed copy is composed of an unfolding chip-board casing built by letter-press maven Brandon Mise, which contains pockets for three accordion books bearing two stories each. The seventh story, which is written by Mr. Greenman with intentional gaps in the narrative, is printed on the casing and does something unprecedented: It invites the reader to contribute to the collection.The fourth pocket in the casing contains a postcard that the reader can use to fill in the gaps in Greenman's narrative and send to Hotel St. George Press for possible publication in future online and paperback editions of the book. This experiment, code-named "The Postcard Project," will incorporate work by authors and non-authors alike, resulting in an ever-shifting, community-created story.
