Tintin et Milou

[TygerFort]

Since this is a jungle scene, it could be from Tintin in the Congo, the Cigars of the Pharaoh, the Broken Ear, the Temple of the Sun, or Tinin and the Picaros. Although he only wears the blue sweater in the last two, I think.
(FYI, Milou is Snowy's name in the original french.)
