These tiny samples are from a very large book of Andreas Gursky's photographs published in 2001 to coincide with an exhibition originating in New York at the Museum of Modern Art, and eventually traveling to San Francisco where I saw it. The enormous prints on the high white walls of our own Museum of Modern Art here have stuck in my mind ever since. Though out of print, the book is widely available used. Prices for not-very-good copies seem to start at around $80, which is a little more than the original cover price. A "collectible" copy is offered at $300.
