Wieden+Kennedy creative Christen compiled his photographic series in a book ‘La Bamba Boo’, supported with seed money from W+K London’s Spore Fund (an internal creative bursary). Over the years, Christen has been capturing people on the streets in Japan, quirky objects spotted somewhere and elsewhere, and time with friends and family; when moments of fun (La Bamba) and melancholy (Boo) live at the same time.
