Occasionally Fiep designed a painting for hoardings at construction sites of shop buildings, for example for 'Modehuis Lampe' and the children’s fashion shop 'Bambolino' in the Kalverstraat in Amsterdam. 


In 1962 Fiep received a commission she thought was very special: a wall painting for the children’s room of the Holland America Line’s cruise ship the Nieuw Amsterdam. She designed three pictures for it: the central panel showed the ship itself, surrounded by all sorts of little boats and ships full of children, on one side was a typical Dutch row of houses with 
pretty façades and on the other a row of New York skyscrapers with lots of children looking out from the windows. As she usually did, Fiep drew many different types of children, including a black one. The client then demanded that the black child be removed, but Fiep refused. ‘I would rather have torn up the drawings,’ growled Fiep, still indignant decades later.

The interior of the children’s room was lost, but the original designs for the wall panels were preserved. On the basis of these drawings and some photographs, a reconstruction of the children’s room was realized for the exhibition 'Getekend: Fiep Westendorp' held in the Kunsthal in 2003.
