Thank you! Michael Kennedy, VW's friend and biographer thought is a good likeness (unlike the Epstein which he thought told us nothing about the composer). I agree that the McFall bust is far superior. I'll try to find some images.
OK - images of VW busts by McFall (top two) and Epstein and VW with Epstein. VW and Epstein got on well and VW invited Epstein to see him conduct Bach's 'St Matthew Passion'. In Epstein's biography there is a nice account of his sessions with VW. Two great artists although, much as I like Epstein's work I don't think much of his head of Vaughan Williams:
Ah thanks, yes those McFall busts are indeed striking. VW seems particularly 'present' in the top one in that photo, to my eyes anyway.
I completely agree about the Epstein, I'd never have recognised VW from it without the context. And it doesn't even seem to highlight or abstract some aspect of him, it just seems like an entirely different person.
