Two boxes made of heavy board and evidently issued in a limited number by the Galerie Buchholz in October 1973 and January 1974, respectively, containing slides of art works, a list of museum events and lectures, and exhibition catalogs from other museums such as Galleria Schwarz in Milan, Galleria Montenapoleone in Milan, Galerie Jean Dols in Liège, Tel-Aviv Museum, and others. The artist featured in both boxes is the Icelandic painter Erró (also known as Ferró or Gudmundur Gudmundsson). Each box has a table of contents at the top.
