Description
based on the catalogue of Kunsthalle Bremen, Ex Machina - Frühe Computergrafik bis 1979
Note: "Sicograph" as a series name is unverified online; the cited catalogue is real (Ex Machina — Frühe Computergrafik bis 1979, Deutscher Kunstverlag 2007, whose Sammlung Franke is at Kunsthalle Bremen) — check the term against the physical catalog.
