Ik heb hier misschien iets over Piet Broos, het komt van een stripsite:
Piet Broos
(1910 - 1964, The Netherlands)
Petrus Jozef (Piet) Broos is primarily known as a freelance writer and illustrator of children's books. He also made a lot of comics, like 'Kees Holland', a story about the Second World War which appeared in May, 1945. He did a lot of work for Catholic journals, and illustrated a few Bible series for children. One of his English publications was 'Gnomie Longnose'. He died in 1964, at the age of 54.
IK denk dat dit dezelfde is die deel 6 geïllustreerd heeft.
