H is from a group of works that mimic the appearance of machine-made units such as heating vents or ventilation grilles. However, it has no utilitarian function other than as a work of art. Opie?s work suggests a fascination with the relationship between art objects and those made for everyday use. His approach is a contemporary take on the idea of the ?ready-made? art object. Opie?s sculpture is a skillful imitation of an existing object which raises new questions about truth and illusion in art.
