Following Arnold Odermatt's Karambolage, On Duty and Off Duty, all published by Steidl, Let's call it a day presents more rediscovered masterpieces by this remarkable selftaught photographer, who trained himself primarily through his duties as a policeman in the small, secluded Swiss canton of Nidwalden. Odermatt thus developed an unconventional artistic fingerprint, which served him well during his working days as well as after hours. Whenever off duty, Odermatt often volunteered to take pictures throughout Nidwalden. He photographed his motifs usually only once, developed prints on demand and then archived them in his attic-all was preserved but ignored. Luckily, the photographer's son has rescued these treasures and ensured their publication. Let's call it a day is the fourth volume in a series of books that brings into focus this extraordinary work.

Arnold Odermatt was born in the Swiss Canton of Nidwalden in 1925. He joined the police force in 1948 and retired in 1990 with the rank of first lieutenant, chief of traffic police and vice commandant of the Nidwalden Police Department. His photographs have been exhibited atthe 49th Venice Biennale in 2001, at the Art Institute of Chicago and at Fotomuseum Winterthur.
