American sculptor Claes Oldenburg is famous for his work in the 1960s and 70s that inflated everyday objects to enormous proportions: safety pins the size of trucks, typewriter erasers ten times life-size (here at the National Gallery of Art), and hamburgers that would have comfortably served Goliath.

BIG/small, one of the current shows at the National Museum of African Art, merges Oldenburg’s vision of the gigantic with a variation on “Honey, I Shrunk the Kids.” The exhibit, a hodgepodge of large and small African artifacts, is designed to stress size differences. But more than that, it is an effective curatorial enterprise that allows viewers to interact with and, in a way, determine the intrinsic nature of the pieces.

One advantage of sculpture over painting is that it allows the viewer to participate as more than a bystander. A painting creates its own world, and it is up to the viewer to either enter that world or alter course. But a sculpture is interactive; the viewer can walk around it and consider every angle and perspective. This establishes a relationship in which the viewer becomes the point of reference for the sculpture.

In BIG/small, a pair of chairs, for example, casts the viewer in the role of reference point. You could hold Weight in the form of a chair in your hand. Made of copper alloy in 18th or 19th century Ghana by an Asante artist, the weight was used by businessmen to measure gold dust. The chair is sturdy and heavy looking, with a pattern of rounded projections emerging along its edges that lends the chair a look as if struck by measles. In a glass case beside the weight is almost precisely the same form—just bigger—of a chair used by Asante royalty.
