Btw there's a reference in a review of an exhibition in New York 1989 of a sketch of him on the way to execuion - has anyone ever seen this, or know who it's by or if it's genuine?
I have a copy of the book they made from that exhibition, which has that sketch, among others. I have no reason to suspect it's not genuine, thought they attribute it to David, which I doubt somewhat, given that he was in hiding at the time. Anyway, I think the only reason they make that attribution is that they assume anyone else would have made a grosteque caricature by that point, and that's not really the case with the drawing. I can post it, if you like, as soon as I get my scanner up and running.
