The book weighs in at 19.2 pounds (27.6 pounds in its display box). It's 17.25" long by 13.5" high and nearly 3" inches thick, plus cover. The pictures are printed on specially produced short grain, 100 lb. cover stock, with a smooth enamel coating.
The grain on the acid- and chlorine-free paper (10% recycled post-consumer content, 'natch!) from Stora Enso runs parallel to the spine when it's run through the Heidelberg presses used. This to provide effortless page turning and prevent stress on the spine, as the paper adjusts to different humidity conditions in readers' homes around the world, the authors say.
