Bruce Onobrapkeya’s works explore diverse themes that includes myths, folklores, post-colonial identity, shrine figures, abstract forms and animals. His innovation of the renowned print-making technique plastograph, a system of ornamentation on zinc-like surfaces or an intaglio, famously described by the artist as ‘’Hydrochloric Acid Accident’’, was succeeded by previous techniques such as bronzed lino relief, a form of relief sculpture that combines basically the object of lino blocks and substance of bronze colour patina.
