Tintin Hardcover - The Seven Crystal Balls

In The Seven Crystal Balls (1948), seven scientists are mysteriously struck by lethargy upon their return from an expedition in the Andes. With Professor Calculus missing, Tintin and the Captain set off in search of him. Created in 1929 by a certain Georges Remi, who was already signing his drawings under the name Hergé, Tintin would go on to have twenty-three adventures whose success, to this day, among young people aged 7 to 77, has never faltered.
