Going on a tangent: Did you read Tintin while living in America? Because from what I've understood, those comics are almost unheard of there. Is that not true?
I've seen many volumes of Tintin at the bookstores in NYC, both independent shops and Barnes & Noble. I also remember them from youth, but wasn't a big fan. I don't think they are super popular, but have been available.
Last summer, I went through the whole series with my kids as bedtime stories (minus Tintin in the Congo and Tintin in America, which are a little beyond my PC threshold). We loved them! I have no idea why every kid in America doesn't slurp them up like candy.
