Cult classic and collector's item, Dali's Mustache is the result of the astonishing artistic collaboration between surrealist Salvador Dal and experimental photography pioneer Philippe Halsman. Dal and Halsman were friends as well as professional collaborators for more than three decades. Subtitled A Photographic Interview, the concept of the book is one short question presented to Dal , which Dal answers, followed by a corresponding black-and-white photograph by Halsman. The photographs are intentionally absurd and hilarious. Early editions of this book came with a warning on the back that said "Warning! This book is preposterous." Question: "I have the feeling, to have discovered your secret, Salvador. Could it be that you are crazy?" Answer: "I am certainly saner than the person who bought this book."
