Watch

Fakes & Markets, Watched

We monitor public sales and listings against the registry and the known cases on file. We describe evidence, never people: a work is either Cat Burglar verified, or it is not yet.

Cat Burglar verified

A Stamp of Approval has been issued on senior sign-off. The certificate verifies by signature.

Not Cat Burglar verified

No Stamp on file. This is the default for every work, and it is not a judgement.

Under review

A case is open; the file is being assembled and framed.

Context only

A known case shown for context. Never a finding about a work in front of us.

Market watch

Listings Against the Registry

The market-watch engine reads public sale and listing pages that permit it (robots-respecting, no logins) and checks each against the registry: title collisions, size matches, claimed exhibitions, and whether the work already sits in a known case. Alerts are written in the house wording and reach a person before anything else happens.

SPECIMEN
Alert · specimen wording

An oil on canvas offered online as “School of Paris, c.1920”, 41 × 33 cm. Title and size coincide with a registry entry; the claimed exhibition has no record on file. Status: Not Cat Burglar verified. Recommended: request the seller's provenance file before any further step.

No live market feeds are connected in this prototype; the alert above is a specimen of the wording only.

Known cases

On File, as Context

Court outcomes are quoted with their source. Acquittals are recorded. A seizure or an investigation is not a finding against anyone.
