Patrick Heron's "Small Yellow: January 1973" is a screenprint that exemplifies his exploration of colour and abstract form. Created in 1973, this work features interlocking shapes in varying shades of yellow and orange, reflecting Heron's interest in the interplay between colour and space. The print measures approximately 16 5/8 x 20 1/2 inches (42.4 x 52.2 cm) and was produced in an edition of 72, each signed, titled, dated, and numbered by the artist. "Small Yellow" is part of several notable collections, including the Tate Britain and the Blanton Museum of Art. This piece is a testament to Heron's significant contribution to abstract art and his mastery of printmaking techniques.
