Frederick Lane Sandback was an American minimalist conceptual-based sculptor known for his Minimalist works made from lengths of colored yarn, drawings, and prints. Though he employed metal wire and elastic cord early in his career, the artist soon dispensed with mass and weight by using acrylic yarn. His work can be considered visionary or imaginative, as well as minimal and literal.
Sigmar Polke was a German painter and photographer.
Polke experimented with a wide range of styles, subject matters and materials. In the 1970s, he concentrated on photography, returning to paint in the 1980s, when he produced abstract works created by chance through chemical reactions between paint and other products. In the last 20 years of his life, he produced paintings focused on historical events and perceptions of them.
