Abstractions, 1960s
Among the sketches from the 1960s can be recognized preliminary sketches for the painting series "Ammonites" (1957-1963), "Anthropoliths" (1963-65) and "Movens" (1965-1973). The repetitiveness of the motifs and compositions attest to their preparatory, working-basis character, aimed at finding the right arrangement of lines and colours, which would later be transposed onto canvas. Some of the abstract sketches were made in pencil or pen and ink, others in watercolours or using a colour marker.
