 In the 1940s and 1950s , when Hergé 's popularity had increased , he and his team at Studios Hergé redrew and coloured many of the original black @-@ and @-@ white Tintin adventures . They used the ligne claire ( " clear line " ) drawing style that Hergé had developed , in this way ensuring that the earlier stories fitted in visually alongside the new Adventures of Tintin being created . Casterman published this second , colourised version of the story in 1943 , reduced from 124 pages to 60 . This second version contained no significant changes from the original 1937 one , although the black @-@ and @-@ white television screen that had appeared in the 1930s version was now depicted as a colour screen , despite the fact that such technology was not yet available .
