Balthazar:
I recall seeing this logo in the book,
Hergé and Tintin - Reporters.
You touch your marble! Just came across a photo of the logo in the aforementioned volume - it's shown as the enamel lapel-badge worn by expedition members, and can be seen on page 50.
Balthazar:
it's maybe shown there in pencil sketch form at the edge/bottom of a Tintin pencil layout,
Again, doffing of the chapeau to m'learned friend! The original design-sketch appears in the margin of a page of
Tintin in Tibet rough pencil art, found on page 130 (of
Hergé and Tintin - Reporters, of course - the pencil art is for what became page 14).
Hergé and Tintin - Reporters continues to fascinate and infuriate me in equal measure, which is possibly one of the reasons it has taken me until now to check it and see where the logo was to be found.
The content is a gold-mine for
Tintin-fans, packed chock-full as it is of art and photos from every stage of Hergé's life and career; however the lay-out and design are
atrocious!
It can be head-ache inducing to try and work-out which caption (if any) relates to what image; the order in which material is included is haphazard, and there's no index.
The caption for the badge tells you that the design is in the margin of
Tintin in Tibet, but doesn't mention that that page of art is included in the book, nor does it display them together, which would seem to me to be the obvious solution.
But, having now located both, I will put it back on the shelf for another seven years, to allow my brain to cool down...! (Here endeth the grumble!)
