We have a page on
Special Cameos in Tintin Books but I haven't found a thread on the subject (apart from a brief mention in
Ottokar here). I'm sure there are a few more that we don't already have in our present list so, if anybody becomes aware of any more, please add them here.
Here are a few I believe could be added:
I think Al Capone may be the only real life
named person ever to appear in a Tintin book (correct me if I'm wrong!) although I know many other real life people are mentioned by name; Napoleon, Columbus, Onassis, etc. Of course there are the cameos from Hergé and his associates but strictly speaking they don't count as they aren't named.
Hergé himself also appears seated with his wife Germaine in the music hall scene
The Seven Crystal Balls [page 16, frame 4]. (They are slighly obscured by a old lady in a hat, bottom left of the frame).
Hergé is also
supposed to be represented in the very last frame of
Soviets somewhere among the scouts, but I haven't located him yet...
Hergé again, although this one is a bit more obscure! All of the planes from the Halchester Flying Club in
The Black Island (1966 version) have a serial number starting with G- (for Georges?) but the
biplane comandeered by the Thompsons has AIRJ as the last 4 letters. (G and J have a reverse pronounciation in French [G=djai & J=dji] but as this adventure is set in the UK it's possibly one for the English-speaking nitpickers!)
