A vibrant woodcut by Damien Hirst from his celebrated Spot series, 'Tryptophan' (2010) features nine evenly spaced polka dots in a range of bold and pastel hues — including red, teal, purple, pink, navy, yellow, crimson, orange, and light blue — arranged in a 3×3 grid on a white ground. Named after the amino acid tryptophan, the work exemplifies Hirst's systematic yet visually arresting approach to colour and pattern. Part of a signed edition of 48, this large-format woodcut (102 × 102 cm) is a sought-after example of one of the most iconic bodies of work in contemporary British art. Listed at £25,000, it represents a rare opportunity to acquire a signed, editioned Hirst print of this scale.
