Les Misadventures de Bécassine ; text by Caumery and illustrations by J.-P. Pinchon.   The character is a guileful yet incredulous maid - along the lines of those fictional retainers invented by Proust and Flaubert. She is drawn with a face like a Jerusalem artichoke, with the tiniest of mouths.   RIGHT from the 1938 collection of comic books by Pinchon and Caumery.   LEFT This is the first page in an extended narrative and interesting for the sudden intervention of the porthole effect - an iris shot to suddenly fix our attention on her feelings.
