One of the characters of Mourning Dove is a portrait artist, and self portraits play an important role in the book.
I am fascinated by Picasso's self portraits. I collected them, showing them together, each approximately the same size. Here they are.
Picasso Self Portraits
Although I don't really care for abstract art, IMHO the most abstract one here, "Facing Death," might be the most powerful. The blue period is great, but then so are the first two.
There's a wonderful collage of morphing Picasso and Van Gogh portraits, many of them self portraits, that you might want to check out at this link.
See my own self portraits are on this blog.
