Typically when Serra draws, it is not in preparation for a sculpture, but to assess what surprises or engages him after one is completed [see also Eight Drawings Related to “Twain” (n. 6)]. St. Louis III , which directly references Twain, was made after the sculpture’s completion. The flat black shape comes close to being equal to the shape of the paper, but falls short. Like one of the metal slabs of the sculpture in downtown St. Louis, a huge black rectangle conveying the weight of steel seems to reframe the spectator’s view. The viewer does not experience an illusionary world, but the paper replaces the cityscape.
