Original mixed media on paper (combination of gouache, oil pastel, and watercolor) is a vivid portrait attributed to Anatoly Timofeevich Zverev (Анатолий Тимофеевич Зверев), one of the most prominent Russian expressionists and a central figure in the Soviet non-conformist art movement. The work, dated '59 and initialed A.Z. in the lower left corner, showcases Zverev's signature energetic brushwork and frenetic composition, focusing on a stylized face with exaggerated glasses rendered in heavy impasto. Zverev was often compared to Western contemporaries such as Jean Dubuffet, Egon Schiele, Chaïm Soutine, and Francis Bacon. His dynamic visual language drew influence from artists like Pablo Picasso, Georges Rouault, and Oskar Kokoschka. This piece echoes the psychological intensity and immediacy seen in works by Willem de Kooning or Emil Nolde. Zverev’s works are held in the Tretyakov Gallery, the Pompidou Centre, and major private collections across Europe and the US. This piece is an excellent example of his early work, created during a pivotal period in his artistic development before he was widely recognized by the international art world. The expressive application of media and daring facial abstraction are emblematic of Zverev's unique vision and mastery. Condition: Very good condition for its age. Some minor surface wear and signs of handling. The colours remain vivid and the paper is stable. Framed behind glass.
