Expressionist portrait from the 1970s

Magnificent expressionist portrait in mixed media (acrylic and pigments) on paper. This modern artwork, with its allusions to ancient Greece, reminds me of some of Picasso's ceramic works. Breathtaking textures and colors. The work is in excellent condition. Note a crease in the middle that almost disappeared when I had it framed. Frame dimensions: 50x50cm. Signed on the back in Cyrillic, but I forgot to take a photo of the signature before having the artwork framed. Sorry.
