The work on the catalogue raisonné is overseen by a scholarly advisory committee


The decision as to whether a work will be included in the catalogue raissoné lies with the Estate and the scholarly advisory committee and will be based on art historical findings.

The following aspects will be considered:

- Documentation of a work through exhibitions and publications

- Provenance and signature

- Visual inspection in regards to material, technique, style


The catalogue raisonné itself is the collection of the results of these decisions that consider the current state of knowledge. All rights to revise decisions to include or not include a work in the catalogue raisonné are reserved; revision can take place at any time on the basis of new findings.

After a decision has been made, a written notice about it can be furnished, if desired. A fee will be charged for such written notices.


We do not provide expert opinions about the authenticity or value of works by Sigmar Polke.
