Amsterdam: International General, 2011
18.5 x 21cm, 1pp. Typed invoice on printed stationery. An invoice for the Jan Dibbets postcards sold to Paul Robertson by Seth Sieglaub’s International General (his print company that often published books on Oriental fabrics). Mostly interesting as the invoice is signed in blue ink by the former curator and prime instigator of conceptual art in the 1960s. Previously folded.
