All works of art from one degree to another are self-portraits even if there is no literal image of the artist to be found in it. The artist will be present in the work. The artist will have put their heart and soul into it.
The literal self-portrait is paradoxically both a lie and the purest truth. The artist will project the image that we want the viewer to see but at the same time will, because we are human, convey our innermost feelings and our vulnerabilities.
Just over a couple of years ago I started a blog, Autoritratto, to showcase my self-portraits (in drawing form, painted form and photographs) when they came along. I do hope you can pay it a visit.
I have a membership subscription to the Art Fund. With it you get a National Art Pass which either gets you into exhibitions for free or at reduced prices. If you gawp a lot at art it’s worth considering joining. I think it offers great value for money. You also get a quarterly magazine which is very informative as well as printing some very interesting stuff. I was very pleased to see that the current issue, Autumn 2019, has an article on the self-portrait. Like a lot of writing about art it’s a bit pretentious but it’s well written. Entitled The Power of the Self-Portrait it says that:
"Artists’ depictions of themselves can be complex expressions of the self. With several upcoming exhibitions featuring self-portraits of prominent artists, Ben Street explores what lies behind their enduring appeal, to both artist and viewer."
They certainly can be 'complex expressions of the self''.
