Francois de Nome - Hell
I've posted this work before but it was a blurry cropping of the original painting. And unfortunately this copy too is a cropping as it has left out much of the right side of the painting that can be seen in the previous posted version. If someone knows where to find this incredible painting online without large chunks of it cut off I'd love to see it!
