This one’s very interesting, to me at least, because it shows Tintin with a problem he almost never has: dealing with the press. Sure, there were a couple occasions where he was offered exorbitant amounts of money for an article he was going to write, but even when he comes back from the moon he has less press coverage than he does on this cover. And it seems he’s most comfortable that way. Especially Snowy looks generally frightened by the mob, but Tintin shows some of that too. The paparazzi may follow Castafiore around, but the leave Tintin alone.
By the way, this cover advertises a contest to win 50 Tintin beach towels. I have no idea how much money one of those would be worth, but I bet they’d be really, really collectible.
