Ketterer Kunst applies scientific cataloging and verification of authenticity of all works on offer with great care. Our team of experts pays close attention to every detail and is in constant professional exchange with international museums, as well as with the relevant institutions and experts.
Provenance research is a key criterion for scientific catalog editing. Our specialists permanently check the provenance of all of our consignments and execute a meticulously documented research. To Ketterer Kunst certainty and transparency are all the more important in cases of changes of ownership dating from between 1933 and 1945.
Additionally, every object, regardless of the estimate price, is checked with the Art Loss Register (ALR) and the Lost Art data bank.
