I’d repeat what Bernard Tordeur said at Greenwich: he has been asked several times to apraise Hergé sketches for authenticity, and has yet to be shown what he considers to be an original…
Michael Turner says something very similar in Chris Owen's
interview.
I agree entirely with your points jock, and concede that it is possible for an artist to reproduce independently a drawing from a previously published work. However in this case I find it hard to believe that the drawing is a true Hergé. I’ll make clear that what follows is my opinion only on the
authenticity of the sketch and does not have any bearing on the seller’s honesty.
A comparison between this image and the relevant one from
Alph-Art (easiest done using the 1986 cover) is fairly clear in showing that the ‘forger’ has used Hergé’s original as a basis. In particular, the line extending diagonally back from Tintin’s left eyebrow, the long nose, and what appears to be a flap of Tintin’s collar. Some licence has been used in converting Tintin’s frown into a half-smile!
If the drawing is a genuine Hergé, we would have to ask why Hergé chose that one specifically for an autograph. Aside from it being chosen for the cover of the first edition of
Alph-Art (something which Hergé had no influence over) I would argue that it’s not a particulary arresting or striking image in its current form. Perhaps it would have been had the story been finished, but in context among the other sketches on page 8 it’s a fairly inconsequential sketch to use again. I find it unlikely that Hergé would depart from his usual practice of supplying a ‘headshot’ of Tintin and Snowy in favour of this one. I don’t recall seeing an example of Hergé’s autograph where he has reproduced an illustration from a book before, but if he were to, I would think it to have been much more likely taken from an already-published work that the recipient would recognise, rather than a work-in-progress.
I’ll repeat: this does not necessarily mean the seller has deliberately faked the drawing and intends to deceive. For all we know they could be selling it in good faith, unaware of its provenance, and may even have wrongly paid good money for it believing it to be genuine. I would add that their eBay description does not claim that they were present when Hergé supposedly drew it, and that the sentence “paper is frayed at the end due I think from being riped [sic] out of the book†suggests that it was given to them by somebody else.

P.S. I did contact the seller and ask them to clarify a few things but so far I have had no reply.
