Hergé did not make use of speech bubbles, an innovation that was yet to become widespread in Europe, and instead his cartoons were accompanied by captions, three to five lines long. He would begin to add simple speech bubbles into the series, stating simple comments like "Eureka!", "Bang!", and "Hip! Hip! Hip! Hurrah!". Hergé later noted that "From time to time... I risked a timid question mark, or perhaps a few stars, when, for example, a character was punched. I must have seen that in "L'Éatant" or "Les Belles Images", the illustrated papers of the time." Hergé had come under the influence of other comic strips, such as those of the French author Alain Saint-Ogan, and British comic magazine "The Rainbow". He was also influenced by the contemporary American comics that reporter Léon Degrelle had sent back to Belgium from Mexico, where he was stationed to report on the Cristero War. These American comics included George McManus's "Bringing Up Father", George Herriman's "Krazy Kat" and Rudolph Dirks's "Katzenjammer Kids". Totor's button nose was influenced by the illustrations in "Bringing Up Father".
