The Hahnemühle Certificate of Authenticity was designed to protect the security and genuineness of your limited edition art works and reproductions on Hahnemühle paper and to reduce the risk of forgery. Each certificate is made of premium deckle edged mould made paper with a Hahnemühle watermark and fluorescent security fibres. A serialized numbered hologram should be added. A second, identically numbered hologram should then be applied to the reverse side of the artwork.

Pigment liner + Graphite pencil

The Hahnemühle Signing Pen Duo combines a high-quality pigment liner and graphite pencil for your unmistakable signature on matt, satin, and high-gloss paper surfaces. The black fine liner with pure pigment ink is indelible, lightfast, and odourless. The archival and waterproof pigment liner impresses with its fine metal tip and makes even the most detailed signatures possible. The classic graphite pen is also black and in archival quality.
