Cat
Burglar
Every work has been somewhere. We prove where, and we say plainly where the record runs out.
Evidence intake, case building, signed certificates and a public registry, under one published standard.
Proof, Not Provenance by Assertion
We read every document, test every claim against the record, label each finding by the strength of its proof, and name every party at every point a work surfaced. Where the record runs out, we say so.
Six Engines
Authenticate
You hold the documents. We assemble the file the recognised authority for the artist expects and route it for an opinion.
Enter →Build a Case
The paper is thin. We reconstruct where the work has been, name every surfacing party with a source, and mark each gap plainly.
Enter →Watch
Public sales and listings read against the record. Anything without a file reads Not Cat Burglar verified, nothing more.
Enter →Consign
Works placed with their file attached: documented provenance, fully disclosed, offered with discretion.
Enter →Art World Map
Artists, houses, collectors and exhibitions, and every documented line between them.
Enter →Research
Archives, catalogues and technical studies, with the open questions that would settle a history.
