Here are two more Tintin references from the 1980’s. Above is a cartoon from pop music magazine Fabiola (from 1985 or 1986, I think, since Fabiola didn’t have that long a run). It shows Elvis and Richard Nixon in a Blue Lotus pose, probably giving drug users, the Beatles, left wing activists and hippies the evil eye.
Below is one from a later date, commenting on the first war in Iraq, which was directed as if it was a movie (remember the embedded journalists ?). I think it is by Jan de Maesschalck, but I’m not sure.
