‘Special class – not for sale’ was a particular category that Klee used within his own system of classification for his works, to which he actually assigned various price ranges.
The label ‘special class’ – ‘Sonderklasse’ or ‘SKl’ – was reserved for those works to which the artist attached particular significance, and which he had planned for his posthumous collection.
This is an area under examination in a research project at Zürich University sponsored by the Ernst von Siemens Stiftung, in collaboration with the Zentrum Paul Klee and Leipzig Museum of Visual arts. The results of the project will permeate the exhibition.
As well as other works by Paul Klee, with 100 ‘special class’ works the exhibition will include about a third of the total ‘special class’ holdings. An extensive publication featuring the research results will be published to coincide with the exhibition. After Bern, the exhibition will be shown in a slightly different combination at the Museum of Visual Arts in Leipzig (01/03-25/05/15).
