Jacek Malczewski (1854-1929) is considered by me, among others, as one of Poland's finest painters. I wrote about his portayal of Death as a woman here, and about his muses here. His Wikipedia entry is here.
This post features some of his many self-portraits. Besides acknowledged self-portraits, Malczewski often included himself in paintings of other subjects. (A currently active artist practicing that sort of dress-up genre is Cindy Sherman, though I'm nor sure she was originally -- or ever -- aware of Malczewski.)
The selection of images below is in approximate chronological order.
This allegorical self-portrait includes a woman who seems to be his sometime mistress and long-time model Maria Bal.
That might be Bal again, at the right.
Another Death-related self-portrait
More Death, perhaps more Maria Bal.
Wikipedia mentions that Malczewski lost sight towards the end of his life, so this might have been painted when that conditon was appearing.
