I found this strip, drawn around 84, and at least that final panel is clearly influenced by Moebius. To make it more obvious I even put in portraits of Major Grubert and Blueberry. The strip isn't that funny so I won't bother with a translation. He starts World War 3 as an april's fool, ha ha. Anyway, this was the short period when I drew with a rotring pen and it shows I really had a lot to learn.
