Throughout her career, Hesse repeated a number of key ideas. One of these was the framing device that first emerged in her early drawings, with their box-like compartments. It is echoed in a series of drawings shown here, mostly executed in the summer of 1969.

Hesse returned to the framing device, paring it down even further, so that there appears to be nothing within the frames but an ephemeral shimmer of subtle colour. Hesse declared that:

I would like my work to be non-work. This means that it would find its way beyond my preconceptions… as a thing, an object, it accedes to its non-logical self. It is something, it is nothing.
