Simply the world's most complete collection of hand dryers. Who knew that something so normal, so instantly forgetful, so remarkably unremarkable could be such a thing of beauty and intrigue? This book, based on Samuel's Instagram site @handdryers, documents a stalwart of industrial design, an item so everyday and prosaic, yet each one with so much vitality. The evocative photographs, taken around the world from Ukraine to Los Angeles, showcase the variety of design, and their relationship to the environment - some ooze nightclub sex appeal and dazzle; some a clinical sleekness; others a work-horse charm. The stories they could tell.
