Certificate of Authenticity.

Every Lost Collective photograph is a verified record of a real place, photographed by one person in Australia and Japan since 2011.

The Lost Collective archive is the work of one photographer, documenting decommissioned buildings across Australia and Japan since 2011. Provenance is what makes a limited edition print a limited edition print.

Every Limited Edition print from Lost Collective comes with a hand-signed Certificate of Authenticity. The certificate lists the print title, the edition size, and the individual number of your print within that edition. It is signed by Brett Patman.

Lost Collective Limited Editions are printed in three sizes:

• Medium editions: 100 prints
• Large editions: 50 prints
• Extra Large editions: 25 prints

Every Limited Edition also carries a C2PA verified manifest, the digital companion to this paper certificate. The manifest signs the file the print was rendered from and records the camera, the moment of capture, and the edit history back to the original RAW. See verified provenance for how it works.

Small and Extra Small sizes are open editions and do not carry an edition number or certificate.

The certificate travels with the print. If you ever sell or gift the work, the certificate goes with it. Keep it somewhere safe.

If you ever sell the print or gift it on, the certificate establishes provenance for the next owner. The signed paper plus the edition number recorded on it is what links your specific print to the Lost Collective archive. Without the certificate, that link still exists (the C2PA manifest signs the digital file) but the physical chain of custody is broken. If your certificate is ever lost or damaged, contact us with the original order details and we will work out a replacement path.

Lost Collective was recognised in the Multimedia section of the 2016 National Trust of Australia (NSW) Heritage Awards (Highly Commended). The archive sits in the documentary record because of how the work was made, not because of how it is sold.

If your print arrived without a certificate or the certificate was damaged in transit, get in touch via the Contact page and we will sort it out.
