Never really had much time to work on this, but the little I spent, I kind of got interested in the whole idea of the "King in Yellow".


I haven't read the original stories but the King in Yellow is a collection of short stories (by Robert W. Chambers) in which a fictional play of the same name drives readers of it mad.
HP Lovecraft includes references to the King in Yellow in some of his stories. He is described as a being in yellow robes with a smooth and featureless "Pallid Mask", which if he removes it would drive you mad.
Now in my rendering I based the mask on an ancient terracotta Baal mask. One version, he covers even part of his mask, and the eyes would be human but with a small dot like pupils to evoke a sense of madness.
I thought the mask and costume would be simple enough for the era, and mysterious enough. There are descriptions of the King without the mask that are very otherworldly, but I imagined that in these movies, specially back then ... whenever he removes his mask you don't really see his true face.
