Dating from June 1971, Wall Drawing 88 is exemplary of Sol LeWitt’s interest in indeterminacy. The piece embraces a dynamic relationship between the artist, the draftsman, and the work itself, in which the parameters of the work are predetermined by the artist, but certain fundamental elements – the direction, number, and form of the lines – are left to the draftsman’s interpretation. Thus, each execution of the drawing differs greatly, challenging the notion that there is one specific realization of an artwork. The boundaries of Wall Drawing 88 extend beyond this wall to the infinite set of hypothetical instances. The wall drawing was created during a period of broad experimentation for LeWitt.
