This centerfold plays with two distinct definitions of the word 'signature.' In printing, a signature is "a sheet of paper folded, or to be folded, into leaves forming a book." It is also, of course, the act of signing one's name (or that written name itself).
When removed from Aperture Magazine's The Photo Book Review and properly folded, this signature is a sixteen-page book designed by Library Candy, a group of artists that meets regularly in the San Francisco Bay Area. While the membership of this group is fluid, at the time of design and publication members included Jason Fulford, Meghann Rippenhoff, Nigel Poor, Lucas Foglia, Richard Misrach and me, McNair Evans. Each Image is a portrait of one group member photographed by another. The pairings were determined by pulling names out of a hat. The profiles on pp. 10-11 are based on the handwritten signatures presented here and were authored by graphologist Ralph Zackheim.
