"The work has been sold at 1,338,509.20 euros, costs included, by a person who wishes to remain anonymous," a spokesman for the auctioneers, Artcurial, told AFP.

 

The previous owner, another Tintin collector, had bought it for 764,218 euros in 2008, which had until now stood as the record price in this domain.

 

While Artcurial had not announced an estimate of what they thought it would fetch this time, a spokesman said they had expected it to break the one-million-euro mark.

 

Belgian comic book artist Herge painted the Indian ink and gouache colour cover for the first edition of the book, which first appeared in 1934.

 

One of only five such works of cover art remaining by Herge, it shows the young adventurer dressed as a cowboy sitting on a rock, his dog Snowy at his side, as three Indians, two wielding axes, creep up behind him.

 

The sale Saturday was part of a larger sale of Tintin-related memorabilia. Over 700 items were up for auction of which some 85 percent found buyers, the spokesman said, adding the sale grossed over 3.3 million euros.

 

In February a Belgian court refused to ban the sale of "Tintin in the Congo", rejecting a complaint from a Congolese man, Bienvenu Mbutu Mondondo, that it was filled with racist stereotypes about Africans.

 

Herge himself, real name Georges Remi (1907-1983), who revised some of the scenes for later editions had himself justified the book by saying it was merely a reflection of the naive views of the time.
