How to use is for artists and art enthusiasts. As an artist, you can manage your works bearing a Hahnemühle Certificate of Authenticity online. If you are a collector interested in a work of art, you can browse the gallery, search for a certificate number and contact artists directly.

As an artist, you need to create an account at once and free of charge. Then you can register, archive and manage your artworks that you have provided with the holograms of the Hahnemühle Certificate of Authenticity 'Rooster' ('Triton' no longer available) shown here.
