The medium used was scratchboard. Annoying, dusty, and tedious process that results in crisp white lines through a thin black coating. The original is somewhat over a foot wide and near to 18 inches high (I think?). Made spring 2007.
I have gotten it scanned and am working on getting prints made. Hopefully this will happen in the coming spring.
since I will be offering this for sale, I have stuck a rather horrible watermark on and only uploaded a small file- sorry.
