Vincent Van Gogh painted numerous self portraits in his short but productive career. This is -- according to the sign next to it -- an unfinished self portrait painted in Paris, in the period when Van Gogh was moving from his earlier dark, earthy and rough Dutch style to an emerging and exuberant Impressionist style.
Looked at up close, the painting looks almost careless to me. See the whitish blob in the left eye, the pinkish stroke that protrudes too far into his mustache, and some blue blobs in the cheek and temple.
But, stepping back, it works just fine, don't you think?
To anticipate questions, the Wadsworth permits its owned works to be photographed handheld and without flash.
