I think this may have been my second attempt to employ the Graphix Duo-Shade art board -- the stuff Kevin and I used for many of the early TMNT books -- to create an illustration back in the early 1980's. I'm pretty sure it was done for Hampshire Life.
I'm showing this one in its "raw" form, just at it looked in the photograph I took of the original, so that the odd contours of the piece of Duo-Shade are clearly visible. I do this to reiterate how -- because this stuff was so expensive -- I would try to maximise the use of every single square inch of a sheet of it. -- PL
