"Blueberry Hill (Cristea 13)" is a large scale mixed media work by Gillian Ayres created in 2003, combining etching with carborundum and extensive hand coloring in acrylic to achieve a richly layered and vibrant composition. This proof impression, printed by Jack Shirreff at 107 Workshop in Wiltshire and published by Alan Cristea Gallery, showcases Ayres' characteristic gestural abstraction through the interplay of printed and painted passages on heavyweight Arches paper. The work exemplifies the artist's continued engagement with color and spontaneous mark making well into her mature practice.
