Hetreau has illustrated the seven deadly sins by personifying them as women dressed by the leading couturiers of the day. What is interesting is that he has also drawn a character in the same drawing to illustrate the seven Catholic virtues opposite the particular sin involved.
What a novel way approach to illustrating the current fashions of the day with a bit of humour also involved. The illustrations are very French and Almost Cocteau like in their appearance. You have to look closely at the detail of each drawing for the humour involved.
As they were done during World War II I am sure that there are some hidden references to the repressed atmosphere felt in France during the German occupation.
