![Can you guess which Valérian and Laureline album this closeup is from? [answer inside]](https://i.imgur.com/GUkQjwY.jpeg){kind=link}
It’s from album #19, Au bord du Grand Rien (At the Edge of the Great Void).
Interestingly, the original art by Jean-Claude Mézières (downloadable here in high-res), was estimated at €25,000 - 30,000 at auction, and sold for €31,200 two years ago!

Ky-Gaï on the cover makes guessing pretty easy.
