FANTASTIC AND STRANGE Max Ernst experimented with amazing techniques to achieve fantastic and strange landscapes. Collage (found materials), frottage (which uses pencil rubbings of objects as a source of images), 'grattage' (in which paint is scraped across canvas to reveal the imprints of the objects placed beneath), and the BIG ONE TO TRY - decalcomania!
