My son is into Tin Tin at the moment, and he asked for the iPad app for one of his birthday presents.
There's quite a geographical angle to many of the Tin Tin books.
He travelled a bit of course, and then there was the issue of stereotyping which was connected with his trip to the Congo, for example.
Check out the official website with details of the new merchandise and other things linked to the boy detective.
I was beaten to a post on this topic by Jennifer Watts, who did a much better job than I would have done anyway with her look at the geographical elements of Tin Tin comics.
She refers to the Frank Gardner programme, which my son has watched through several times now, and is soaking up lots of detail on Herge and the background to the creation of the stories.
