I recently unearthed a sketchbook that I took with me to Europe and the Middle East thirty years ago. One thing that strikes me is that my cartooning from that period seems still unformed and riddled with mannerisms, whereas my attempts to sit down and draw something attentively usually have more to recommend them. I was never patient enough to develop the skills of a first-rate draftsman but in these drawings I detect some talent that was there from the beginning.
Cartooning, by contrast, is informed by observational drawing but takes off on its own flight of invention. Two things more than any others have focused and strengthened my cartooning: my sojourn as a caricaturist at Ontario Place, which had me wielding a marker as if it were a brush and discarding all cross-hatching in favour of a bold line; and my animation training and practice, which fostered a structural and dimensional solidity (to a degree) in my cartoons.
Here is a drawing from that 30-year-old sketchbook: the Belvedere Torso, sketched at the Vatican Museum.
