PARIS (AFP): A watercolour of the graphic novel hero Corto Maltese has sold at auction for a record 391,800 euros ($485,500), just months after a Tintin strip set a new world high for a comic of 2.65 million euros. The artwork for a 1979 French edition of Corto Maltese in Africa – “Corto Maltese - Les Ethiopiques” – went for more than twice the original estimate, the French auction house Artcurial said Sunday. Maltese, a sophisticated sailor adventurer whose stories are set in the early decades of the 20th century.
