Q4: Which book is shown to Tintin?

As you all know, in Cigars of the pharaoh Tintin is shown his own adventure Destination Moon. In the first color edition the book shown is Tintin in Congo. But which adventure does Tintin see in the original black/white edition?

I believe it was Tintin in America from what I recall.

That is absolutely right Tintinrulz. Haven't read any information about why Hergé switched to Congo for the color version though. The change later on to Destination Moon I guess was made as a paradox joke. The question is yours Tintinrulz.
