From 1949 onwards there was a children’s corner, ‘Parool-Junior’, on the women’s page. From 1952 onwards the corner became half a page and the adventures of Jip and Janneke appeared in it. There was one column available for this feature by Annie M.G. Schmidt and 
Fiep Westendorp. To make the illustration conspicuous, Fiep decided to draw the two children in silhouette. Fiep’s collaboration with Annie M.G. Schmidt, which began at this point with Jip and Janneke, would continue until Annie’s death in 1995. In the meantime, Jip and anneke have celebrated their fiftieth anniversary. 



Of her collaboration with Annie, Fiep said: ‘I always loved working with Annie. There was nobody I clicked with as well as with her. I think it was mainly humour that united us, but there was something else as well: our insecurity. If I read out a text Annie had written, she would ask: “Do you really think it’s funny too?” That was very important to Annie. Vice versa, I was glad if Annie looked at my drawings through those funny big glasses of hers and burst out laughing’. Fiep and Annie were always in very close touch about their work. ‘If Annie had something in mind, she would ring me up and say, I’m going to do this or that. Then with that information I would start to draw and it turned out that we could work with each other even without the literal text’.
