A dynamic and expressive abstract composition, T1966-e21 showcases Hartung's masterful command of gestural mark-making through bold, sweeping strokes of vinylic paint layered across the canvas. The grattage technique — where paint is scratched and scraped away — reveals tension between creation and erasure, producing a raw, energetic surface of contrasting light and dark tones. The result is a work that captures both spontaneity and control, reflecting Hartung's signature exploration of movement, rhythm, and the physical act of painting.
