How does Farr (1991) justify Tintin's appeal to adults? (Week 1)

I believe Tintin appeals to both adults as well as young people because Herge tells it from the point of view of a young adult who is none other than Tintin himself. He is often carried off into various adventures under certain events and circumstances. Many young people are fascinated by adventure stories and the age and portrayal of the character of Tintin also pulls adults into reading his stories. Adults are also pulled to Tintin because Herge incorporates many real-life events and references to history in his character's adventures, something which many adults will be familiar with. Also thanks to the depection of the character of Tintin "the child will be gripped by the excitement of Tintin, the comedy even farce. The adult will aditionally find political satire and parody, puns and prescience" (Farr. M. 1991, Tintin: the complete companion. pgs 8-9)
