Oshrit was born in Poland in 1947 and came to Israel in 1957. She is a mother of 3 and a grandmother of 5. Mintz studied English Literature at the Hebrew University, Theater at Tel-Aviv University and Art with the painter Hava Amit, with whom she studied for two years, and at the Art school ‘Ha-Studio’ in Ra’anana with the artists Hanita and Gabby Ben-Zano.

At the beginning of her artistic way she painted realistic paintings especially portraits and nudes. She also painted abstracts. Now she paints mainly in two styles: Surrealism and Minimalist Abstract.

In Oshrit’s Surrealistic paintings she creates absurd and sometimes complex images connected with her life and the lives of women in general, a subject close to her heart both conceptually and emotionally. Their style is realist, but the absurd images gives them a strong emotional impact. In many of them she uses her body as an object, or different feminine images, sometimes combined with ancient landscapes. Their technique is watercolor.
In her Abstract paintings, painted in oil, despite their minimalism there are many layers of paint, one of top of the other, creating ‘peeping windows’ to the previous layers. The massive paint expresses strong emotions, while the format restrains them. This expresses the polarization between an outburst of emotion and its restriction by formal life inherent in Oshrit’s inner world.
