The PK71 is comprised of three nesting tables that can be stored underneath one another. The tables and their continued, three-dimensional form represent the first time Kj?rholm used the square in all three dimensions of his work. They can be seen as the precursor of his larger and more complex tables. The toy-like character of the small and abstract tables makes them very dynamic and invites you to move them around. Kj?rholm often stacked the naked frames as sculptural symbols to illustrate the elemental quality of his other work. The importance of the PK71 is illustrated by the fact that the tables are included in the permanent collection of the Museum of Modern Art in New York. The tops are made of either black or white acrylic and the square base is in satin-brushed stainless steel.
