 The orange background of this panel is brighter than the hues rendered in the other frames, and the figure's neck opens up into a row of teeth, while a protruding ear juts out from behind its lower jaw.This panel closely resembles an earlier painting by Bacon, "Untitled, c. 1943", which was thought destroyed until it re-emerged in 1997.Inspection under infrared has revealed that the panels were heavily reworked during a number of revisions.
