The poster was commissioned by Casterman publishers and is valued at up to 700,000 euros. It shows Tintin holding the covers of several albums.
The last cover that Hergé drew for "Le Journal de Tintin" that was published in 1978 is also being auctioned. The print shows various characters from the Tintin series and is expected to fetch up to 400,000 euros.
2.65 million euros is the record for a drawing by Hergé last year.
