This darkly comic graphic novel is the second in a series written for the Louvre. It tells the story of an art "expert" who visits a museum to appraise the collection and is taken into the vast basements of history. Mathieu take aim at those who take creations of artists too seriously of course all in good fun. This is definitely an adult title but well worth the read. Look up the first in the series, Glacial Period by Nicolas De Crecy as well.
