Painted in 1938, Self Portrait with Hat and Voile is emblematic of her later “realistic” style. Features that help to define a painting’s realistic appearance are usually accurately rendered shadows, light, textures and colors. We believe the sitter’s physicality and presence. We relate in a similar fashion to the painted semblance as we would to the actual person. Her face is roughly life-sized, looking out at us with heavy eyes, but if it wasn’t for the veil, her painting would be far more ordinary. There is an incredible gestural richness and variety in the veil’s make-up. Toward the edges of the veil, individual strokes adopt the (impressionistic) qualities of moving water or swaying grass. Her face, on the other hand, is treated much more lightly. The veil is transparent here. It feels airy, porous and light.
