Untitled, Hamra on paper, 30x42 cm, signed and dated 1997, a masterpiece from the collection of the estate of the painter Avner Katz, rare and uncommon at auctions, Micha Ullman, Israeli, born in 1939. For his work he won the Israel Prize for Sculpture in 2009. Micha Ullman was born in Tel Aviv in 1939. Between 1964 and 1960 he studied design and art at the Bezalel Academy of Fine Arts. In 1966 he returned to Israel, after a year of study in London. During the 1970s, Ullman created earthworks and other artistic actions that were influenced by both American conceptual art and ecological-social approaches. Many of these early sculptural works involved digging in the ground. During the 1980s, the house became a central motif in his work. In 1980 he exhibited in the Israeli pavilion at the Biennale of Venice's "Third Reserve". Beginning in the 1990s, Ullman's work increasingly included references to the concept of time in sculpture, to history in general, and to the Holocaust in particular. The images of the voids and structures he created emphasized the dimension of emptiness and lack in human structures. Ullman exhibited in the best galleries and museums in Israel and around the world. He won countless awards for his work.
