No Export for You: Only two albums have been officially translated, and one of those was only because it introduced The Smurfs. Papercutz is in the process of translating the Smurf-related stories to be included in their Smurfs Anthology series.
Outlived Its Creator: Though only four volumes came out after Peyo's death. The first three written by Yvan Delporte and the last one by Luc Parthoens.
Referenced by...: Peewit has a cameo in Pierre Tombal where his tomb stone reveals that he is the man buried with his flute, according to his last wishes.
Sequel Gap: Le sortilège de Maltrochu (1970) came out 6 years after Le pays maudit (1964). Then La horde du corbeau (1994), written by Yvan Delporte, came out 24 years after Le sortilège de Maltrochu.

Keep Circulating the Tapes: A few Johan and Peewit episodes are available in the United States on DVD and download; the rest were released on The Smurfs (1981) DVD sets only in Germany.
Screwed by the Network: Subverted, however. The series was dropped after the second season, but the characters weren't. They continued to appear in The Smurfs cartoon show until Season 8 (with Homnibus getting the most appearances).
