Described as a "world atlas against disappearance," this artist"s book from Cyprien Gaillard (born 1980) presents 900 Polaroid photos, arranged into diamond-shaped grids, of architectural dilapidation, from ancient times to the present. Approaching the world as an archeological dig, Gaillard unites form with content by using an analogously outmoded instrument--the Polaroid--to depict these ruined or about-to-be ruined buildings.
