My all time favorites are:
The Incal - Moebious & Jodo
Before the Incal - Janjetov & Jodo
The Meta Barons - Giménez & Jodo
Fragments of the Encyclopedia of Dolphins - Prado

What do you think about those and what are your favorites?
TIL that Valerian is called Ravian in dutch - interesting! What do you think about the new alternative coloration of The Incal? Which one did you get for yourself?
