A while ago the Fundatie Museum in Zwolle presented a small exhibition showing a number of orginal illustrations made by Fiep Westendorp (1916-2004). Westendorp was a very well known Dutch illustrator for children's books. The drawing above is a nice example. The text ('t is altijd Big Ben weer!) means: it's always Big Ben weather!
Three generations (including myself) grew up by knowing her for her drawings in B&W in 'Jip en Janneke', a series of children's books written by Annie M.G. Schmidt. They tell about the lives of 2 children, together wit Takkie the dog and Siepie the cat. The books are known for its simplicity and wit, and are still popular these days.
