This is one of my favourite Tintin comics, I probably read this one the most in my youth, and it's easy to see why. A mysterious island, giant lizards, aliens abductions, and Tintin with a machine gun. It's kind of surprising considering today's standards for appropriate content for kids, but Tintin seems to get a gun in nearly every adventure he gets involved with. I'm starting to see where some of my influences started.
It was hard to settle on a panel from this comic, but I think this sums up a lot of the appeal Tintin has for me.
