The article was casting some doubt on his suicide. I hadn't heard of this German Expressionist before and just loved this painting that was reproduced for the article so googled a few more.
I didn't have much success getting images that I could download but I thought this one was very interesting.
Almost makes me feel like fiddling about with painting again. I haven't used much purple or pink in my paintings (although looking around I see I've used them quite a bit after all) but I'm very attracted to those colours and how they're used in this paintings.
