Super Tree I scratched this one out after a co-worker and I made a few cracks about genetic selection in tree improvement. Trust me, it was only funny at the time. I sketched Super Tree! on notebook paper with a #2 pencil, then inked him with a black ball-point pen. The joke was so funny, I scanned the original and did a bunch of digital work to it. Still could be better, but it’s nice. Also, notice the image is desktop-ready…enjoy!
