Whereas the original version had included Sheikh Patrash Pasha showing Tintin a copy of "Tintin in America", in the 1955 version this was changed to the earlier "Tintin in the Congo", and Hergé would change it again in 1964 for subsequent printings, this time to "Destination Moon" (1953), an "Adventure" set chronologically after "Cigars". Benoît Peeters exclaimed that with this scene, the reader can imagine Tintin's surprise at encountering an adventure he had not yet had and which included the characters of Captain Haddock and Cuthbert Calculus whom he had not yet met. Another anachronism in this version appears when Snowy refers to Marlinspike Hall, the ancestral home of Captain Haddock, from the much later volumes of the series. Harry Thompson opined that the most important changes to the book were artistic, for in the late 1950s Hergé was at the peak of his artistic ability.
