The legendary boxing champion Muhammad Ali is at the center of artist Stefan Banz's photographic documentation of a unique project. During the artist's travels between 1999 and 2001, throughout more than a dozen European citites, Banz asked more than 350 people to adopt their favorite Muhammad Ali pose. Even though they were all imitating the same figure, not one of the depictions is alike, revealing much about the character of the individual--man, woman or child. This spontaneous street sparring developed as a new form of portrait photography; shown here are 63 images from the Ali series.
