The common denominator for the works in this auction is that they are made on paper. The time period spans the entire 20th century. Paper is a versatile medium used in drawing, watercolour, collage, printmaking and mixed media. Drawings can be created with pencil, charcoal, ink or pastel, while watercolours utilise the paper's ability to absorb water and pigment in a vivid way. Collages combine different paper materials and textures to create new visual worlds. Printing techniques such as etching, lithography and linocut use paper as the final medium for graphic prints. Despite its seemingly simple nature, paper offers great opportunities for creativity and experimentation.
