Well, I have already discussed the censorhip of Tintin albums in Iran, but as many of you know, the Americans too asked Hergé ´o "modify" a lot of the books before publishing them.
Among many changes, they asked him to replace black people with white people. For instance, they didn't like a black person beating the captain (who is white) and enjoying it! So they asked Hergé ´o change him, and the result is a middle-eastern looking guy now!
Another more ridiculous example is the following sequence, where they asked Herge to remove the panel which actually shows the Captain drinking!
Equally ridiculous as the Iranians I guess, but at least they did it when Hergé ·as still alive and asked him to make the changes himself, the Iranians are doing it on their own, even without permission from Casterman or Moulinsart.
By the way, I've always thought Hergé ·as too lenient when it came down to this stuff and did whatever the publishers asked him to do, I think he should have stood his ground more firmly, at least in some instances.
