I have a couple of 'artists proofs' of his.
The subject in the 'Fascist Killer' print is nobody specific; but rather an archetype of the musician/rebel/folk lyricist, etc.
The source image for this print has been established as a Peter Webb photo of Denny Laine (Moody Blues, Wings) taken in 1967.
The US flag one is worth quite a lot from what I can gather. FUck knows I need some sort of pension!
Not 'paintings' of course, but neither are the Ravilious pics.
