Peter Halley's *Yellow Prison with Underground Conduit* features his signature geometric abstraction, presenting a bold yellow cell-like form connected to a subterranean conduit rendered in vivid, synthetic hues of acrylic and Day-Glo paint. The textured Roll-a-Tex surface adds a gritty, industrial quality to the composition, reinforcing Halley's critique of social confinement and the hidden systems that govern modern life. The work exemplifies his Neo-Geo style, using stark, diagrammatic forms to evoke the invisible infrastructures of power and control embedded within contemporary society.
