Just scanned this sketch so I can print, trace and reinvestigate. Sounds like a detective story! This is a very old drawing that I glued to the front of a small sketchbook, but the image is one that I've used over and over. And I plan to use it yet again.
The tree its based on was quite anthropomorphic and lived in a New Jersey forest. Right now, his face is a mask of horror because he saw the check I'm shakily writing to the IRS. Two more days to tax time, folks.
