Bienvenue sur la Lune, Mr.Armstrong! by Hergé, via scienceisbeauty:
In 1969, Hergé was commissioned to draw this picture by the Dechy advertising agency. Like Neil Armstrong, Tintin remained unassuming upon his return to Earth.

I grew up readying my uncles copies of Tintin. I remember the radio play of them going to the moon. Ah nostalgia :)
