There is an illustrated children's book by JULIE VIVAS
called "Let the Celebration Begin"
It is about children in a concentration camp.
It is about innocent children's play during horrific experiences.
The illustrations are wonderful and rag dolls are the main theme.
Julie Vivas is well known in Australain children's literature circles
for the illustrations for Mim Fox's "Pussum Magic".
Any good bookstore worth its salt should be able to get copies.
I think Puffin are the publishers. Her illustration method is worth
while studying too.
