This distinctive image of a rectangle with an angled shape at the bottom is seen in several of Beuys's drawings. Rather than simply being just an abstract shape, the image is intended to create a sense of warmth, as the viewer imagines the chunky pieces of felt. Fat has also been used to make this drawing, the other element Beuys liked to work with. Like felt, fat conjures up a sensation of insulation and warmth. Both materials also refer to the body, as felt is made by compressing fibres or hair.
