This is the cover of the a Flemish edition of ‘The adventures of Tintin * The Blue Lotus’ by Herge.
This is an extract from an article Graham Reid in the New Zealand Herald about Tintin’s 75th birthday:
“Tintin – with his faithful canine companion Snowy and the accident-prone, dipsomaniac Captain Haddock – continues to delight, amuse and educate three-quarters of a century after his Belgian creator Georges Remi (who wrote under the name Herge) committed him to print on January 10, 1929.
Back then he looked slightly different as he boarded a train for the Soviet Union as a star reporter drawn for a cartoon in Le Petit Vingtieme, the children’s supplement of the Belgian Catholic newspaper Le Petit Siecle. The flick of hair didn’t come until later when he was accelerating away from the Berlin police in his open-top Mercedes.”
