Tintin

Ah yes, we have seen Quick and Flupke here, on The Beret Project, but Hergé drew up a lot more berets for the stories of Tintin, his most famous character (since 1929).
Tintin is a young reporter who is drawn to dangerous international intrigues in which his quick thinking, bravery and chronic good luck save the day. Almost every adventure features Tintin sent off to investigate an assignment, but rarely does he actually turn in a story without first getting caught up in an adventure. Although the strip was Belgian, Hergé was inconsistent or vague about assigning Tintin a nationality, depicting him instead as broadly European.
