Aside from Enid Blyton, one of my favorite childhood treasures was Tintin, a series of comic books about a young reporter and various adventures he gets into with his friends.
First published in 1929, the series consists of 24 comics. I spent three collecting nearly all the books, my favorite being Destination Moon and Explorers on the Moon.
What I loved about the comics was the adventures and the different cultures that Tintin got to experience. And who couldn’t help but love the bumbling Professor Calculus!
