The Hahnemüehle Certificate of Authenticity is a document that allows you to authenticate limited edition artwork and reproductions. The certificate has been designed to protect the security of the artwork and to prove that it is genuine.
Each certificate is made of premium mould-made paper with deckle edges and features a Hahnemüehle watermark and fluorescent security fibres. This pack of 25 certificates includes 50 holograms. The certificates can be used with laser and inkjet printers. Once a serialised numbered hologram is added to the certificate, the corresponding identically numbered hologram should then be applied to the reverse side of the artwork. This combination of certificate and hologram assures that each Certificate of Authenticity relates to a particular piece of art.
