Here are a few images from a 16mm cartoon, "Jonny Quest: The Curse of Anubis"...
For those unfamiliar with the show:
Jonny Quest was an animated adventure TV series from the 1960's created and designed by comic-book artist Doug Wildey. Maybe somewhat similar to Tin-Tin?
Jonny was involved in all sorts of adventures with his scientist father, his friend Hadji, dog Bandit, and family friend Race Bannon.
Looking at the last image, reminds me how there is absolutely no way a gun would be shown in a kid's cartoon if made today....
