Felix Gonzalez-Torres produced meaningful and restrained sculptural forms out of common materials. “Untitled” (Portrait of Ross in L.A.) consists of an ideal weight of 175 pounds of shiny, commercially distributed candy. The work’s physical form and scale change with each display, affected by its placement in the gallery as well as audience interactions. Regardless of its physical shape, the label lists its ideal weight, likely corresponding to the average body weight of an adult male, or perhaps the ideal weight of the subject referred to in the title, Ross Laycock, the artist’s partner who died of complications from AIDS in 1991, as did Gonzalez-Torres in 1996. As visitors take candy, the configuration changes, linking the participatory action with loss—even though the work holds the potential for endless replenishment.
