Dan Hipp of The Amazing Joy Buzzards has drafted this awesome fake cover to one of Tintin's never-was adventures. It looks like he's in for a rough time, but hey, he's been to R'lyeh and Innsmouth. He'll come up aces.
I bet in this book we learn that either Thomson or Thompson is a Weyland-Yutani android, see Captain Haddock go on a whiskey bender with a power loader ("Zillions of xenophobic overzealous xenomorphs!"), and witness Bianca Castafiore wield a flamethrower. Click on the below image to see Hipp's art in its full acid-blooded glory. Hat tip to Zero!
