An original page of artwork from Herge's Tintin in Tibet has sold for $397,000 at Christie's in Paris.
The lot led a sale of illustrations on April 5, achieving an increase of 80.3% on its estimate. The price marks a new auction record for a pencil drawing by the legendary Belgian artist.
The page was executed in pencil in 1960 and features a wealth of notes that offer a fascinating insight into Herge's creative process.
The Adventures of Tintin was first published Le Petit Vingtieme, a children's supplement accompanying a Belgian newspaper.
The series went on to become a global phenomenon, with over 200m copies of the various books of the series sold in 70 different languages.
In 2012, the origin cover art for Tintin in America sold for $1.6m at Artcurial in Paris - a world record for a piece of comic book art.
An illustration by Albert Uderzo, co-creator of the Asterix and Obelisk series, made $265,362 - an increase of 13.5% on its $233,644 estimate.
The piece was created for the cover of Asterix and the Soothsayer (1972), the 19th volume in the popular series.
Uderzo, alongside writer Rene Goscinny, published the first book in 1961. Since then over 325m copies have been sold worldwide.
The event marked Christie's first ever comic book art auction.
