It is a true challenge to try and find something about this artist Sa0-Chang, as well as finding art. I managed to built a real small collection and hope in time to be able to expand it.
Books illustrated by Sao-Chang:
Les Asservies de Slave Island (1935)
Férocités sensuelles (1935)
Tortures et lubricité (1935)
Le Couvent des tortures (1936)
Goules et vampires (1936)
The artist also did some books together with Lany-R
