When the Spanish Civil War broke out in 1936, Taro travelled to Barcelona, Spain, to cover the events with Capa and David "Chim" Seymour. Taro acquired the nickname of "La pequeña rubia" ("The little blonde"). They covered the war together in northeastern Aragon and in the southern Córdoba province. Always together under the common and using the bogus signature of Robert Capa, they succeeded in publishing through important publications (the Swiss "Zürcher Illustrierte", the French "Vu"). Their early war photographs are distinguishable since Taro used a Rollei camera which rendered squared photographs while Capa produced rectangular pictures using a Contax camera or a Leica camera. However, for some time in 1937 they each produced similar 35 mm pictures under the label of Capa&Taro.
