“The Drinker" is one of 26 paintings that make up the “Grey Series” (1985-88) by Wolfgang Lettl.
The basic concept of each painting is the framing box. An image supposedly painted on paper is stuck to its back. Various objects are lying on the frame.
Different variations of a classic style element of surrealism are used experimentally in this series: Paint objects that don't go together in an unreal space, and you will get surprising compositions that may be more or less meaningful.
