Certificate of Authenticity & Artwork Care

Every original painting by Liis Koger is accompanied by a Certificate of Authenticity, verifying its title, year, dimensions, medium, and artist’s signature. This document serves as proof of provenance and ensures the work’s long-term value and collectability.

Each piece is crafted with professional-grade materials designed to last generations. To preserve its brilliance, avoid direct sunlight, humidity, and sudden temperature changes. For framed works, use acid-free materials and handle only by the frame or edges.

Every artwork is an original, created and signed in Tallinn, Estonia.
