Just another nice detail that you can find in good comic books:
See the picture above? It's called "Le Radeau de la Medusa" by french painter Théodore Géricault about a tragic real story of the 15 survivors of a famous shipwreck in the 19th century and the moment they are finnaly rescued. The second one is a panel form the well known comic Astérix in a totaly diferent context. See the resmblences?
Furthermore, there is a linguistic pun profered by the pirate captain: "Je suis Medusé" that roughly translates I'm stunned but also takes a jab at the original painting.
A couple more drawings made while travelling in Spain.
