DCD is the real thing - the original objet d'art Deep Cheque Document, numbered and authenticated high resolution print, on archive paper or a waterproof, matt white, paper-like substrate, A4 (297 x 210 mm).
Come to think of it, it could also be laser-etched on zirconium, it is, after all a one-off output of a digital file.
Since 2022 those Art Objects come in two flavours - in ›Versioned Edition
each print is unique and individual elements can be added, as requested by the buyer, in ›Counted Edition
all prints look the same.
