It is a portrait of van Gogh, but not a self portrait,
The "hand" or touch is completely different as are the use of colors, which more resembles Renoir's soft touch.
It's a pastel and van Gogh hardly ever did pastels.
I think it's a portrait by Donnadieu (spelling?) as the signature on the back says it is.
