A trustworthy certificate for every kind of work.
Attesian certifies work across every medium — and how certification works is tuned to each one. Image fingerprinting is strongest for flat work and treated more carefully for three-dimensional and editioned pieces. Choose your medium to see how it applies.
Paintings
A painting's value rests on two things: that it is genuinely by the artist named, and that its history holds together. Attesian gives a painting both — a signed certificate of authenticity and an append-only provenance record that starts the moment you register the work.
Drawings
Drawings are often the first works to lose their paperwork and the hardest to attribute years later. Attesian fixes the record at the source: register a drawing and it gets a signed certificate and a permanent, append-only history from day one.
Works on paper
Works on paper — prints, watercolours, collages, and mixed sheets — span unique pieces and editions. Attesian certifies both, and is careful to represent editions honestly rather than implying every print is one of a kind.
Photography
Photography lives and dies by the edition: the same image may exist as several signed, numbered prints. Attesian certifies photographic work while being explicit that identity within an edition comes from the record, not the picture.
Sculpture
Sculpture is three-dimensional, so a single photograph can only ever capture one view. Attesian certifies sculpture with a signed certificate and an append-only provenance record, while being candid that image fingerprinting does less work here than it does for a painting.
Ceramics
Ceramic work is three-dimensional and often produced in related series, which makes an honest record more useful than a falsely precise one. Attesian gives each ceramic piece a signed certificate and an append-only provenance record.
Textiles
Textile and fibre works are dimensional, drape differently in every installation, and are easily under-documented. Attesian gives a textile work a signed certificate and an append-only provenance record so its authorship and history are fixed from the start.
Mixed media
Mixed-media and assemblage works combine materials and often defy a single clean photograph. Attesian certifies them with a signed certificate and an append-only provenance record, and represents their identity honestly.
Craft
Craft and applied-art objects — from furniture to jewellery to decorative work — deserve the same trustworthy record as fine art. Attesian gives each piece a signed certificate and an append-only provenance record.
