Dupuy and Berberian

Philippe Dupuy (born 12 December 1960, Sainte-Adresse) and Charles Berbérian (born 28 May 1959, Baghdad) are French cartoonists most famous for their series of Franco-Belgian comics albums featuring the character ''Monsieur Jean''.

Their collaboration is notable as they share every aspect of creating their stories, from plot through layouts, pencils and inks, to the extent that it is impossible to detect who is responsible for what. But in 2003, they decided to again work on their own, and have since published solo material like ''Hanté'' by Dupuy in 2005. Provided by Wikipedia
