These images are presented with deep humility, in hope that they are worthy of the Spirits they carry. Most of the originals are brown on brown, as seen in some, but many have been processed with modern software (is there any other kind when we're referencing images that may be 6,000 years old?) to restore some of their original power. Think, when they were created, they were the very pinnacle of expression! The idea of reproducing concepts at any level in two-dimensions was brand new! It is very difficult for us, surrounded 24/7 with artificial stimulants, to imagine such a time and sensation. But they are our ancestors and each of them is shown with pure respect.
