I think he was in Vogue a couple of years ago and I have always thought about these paintings and wished I could remember who did them, now I have found them. They are so cool looking. Here's an exerpt from NYTimes:
Born in England and living in New York since 1974, James Nares does non-objective painting in single gestural strokes, often using brushes he makes himself. According to New York Times art critic Grace Glueck, the effect is that of a combination of "the intricacies of Japanese calligraphy" and 1960s paintings by Roy Lichtenstein in that they are "a little cartoony, inevitably evoking (his) giant brush strokes". . .
