Roj Friberg, "Katalog, skisser och kommentarer till grafisk mapp med 15 blad inspirerade av August Strindbergs Spöksonaten : utförda under åren 1988-93", Duro Grafiska, Stockholm, 1994. Illustrated p. 12.

Roj Friberg was born in Uddevalla, he began his artistic career while studying at the School of Arts and Crafts in Gothenburg to later continue at Valand Academy from 1961 to 64. Friberg uses several distinctive techniques. He mixes graphics, drawing, painting. He utilises unconventional tools such as dentist drills. His works can be executed on specially prepared canvases, such as lacquered or etched ones. His visual world is both strongly realistic and dream-like. For a period of time his choice of motifs were relatively political and "alltogether protest-base", such as his famous work "Juntan" from the 1970s. Roj Friberg is represented in several of Sweden's greatest museums and has even done several charitable projects, such as at Östra Sjukhuset in Gothernburg.
