Not quite a Scribble

So this isn't really a scribble. It is actually the only evidence I have of an image I did as a commission about 12 years ago from a WW2 era image for a client I do not remember other than the fact that he attended one of those for-profit night-schools for "working professionals" (basically a degree mill).

It was drawn and toned in ink (Maybe Higgins, maybe Rotring) using a croquill pen and various brushes IIRC.
