Jon Foster’s newly updated site is still a little skimpy on background, and I don’t know a whole lot about him, except that I’ve admired his paintings in the Spectrum collections, seen some of his comic covers for DC and Dark Horse, and I like his work.
He sometimes works almost (but not quite) monochromatically, sometimes in a painterly approximation of duotone, and sometimes with a rich palette. His style can be brusque or refined, ephemeral or textured with the grit of reality, but is always visually captivating.
His site includes a nice selection of his illustrations, some sketches and even examples of sculpture.
There was a book of his work called Progressions; The Art of Jon Foster, but it’s unfortunately out of print. A new book, as yet untitled, is due in the coming year.
