Frank Auerbach's "Christmas Tree at Mornington Crescent" is an expressionistic work that captures the festive subject through the artist's characteristic thick, gestural brushwork and densely layered paint application. The composition depicts a Christmas tree in the London location of Mornington Crescent, rendered with Auerbach's typical intensity and emotional immediacy rather than representational clarity. The work exemplifies his approach of repeatedly reworking the canvas surface to achieve a sense of psychological presence and material richness.
