I'd have to go for Asterix &....Obelisk? Heh, not quite a freudian slip but theres some sort of pun in there...Menhir spelling mistake...something, something ...Obelix, big standing stone, punchline. Yeah, I'm not good at this.
I like tintin for that classic Adventure story feel, but I just have more time spent with A&O, they feel like an old friend.
I think I'm going to have to go down to the Library this afternoon...
