bryan nash gill takes incredible wood prints from (surprise!) actual pieces of wood. the man must be insane with the prices he dreams up, but isn't it delightful that through the power of the internet you can see this lovely thing without purchasing it?
what is super interesting about this print, though, is the weird tree ring pattern going on here. each one of those rings grows uniformly around the tree every spring and summer, but Gill carves slight bumps and ridges into the face of the stump to get those tight clusters of rings. you can see how he made it here or (have lotsa dollars?) buy it here.
