Danny Matthys
Danny Matthys creates an “in situ” work for the twelfth edition (February 1976) of the art journal +-0. He creates a supplement to the journal, which includes photo reproductions of all the pages from the journal.
Matthys’ name is not mentioned in the supplement. Only when edition “12 bis” (May-June 1976) is distributed, to which Matthys adds another multiple, is his identity revealed through the signature on the multiple.
