International accounts often call these works fantasy coffins. The Royal Ontario Museum's interpretation uses the local term abebu adekai, translated as containers of proverbs. That language encourages a viewer to ask what a form communicates, rather than assuming that a recognizable car, fish or airplane is merely a visual joke.
Literal resemblance is only part of the explanation. The ROM's Mercedes-Benz-shaped coffin, commissioned from Paa Joe's workshop in 2009, is interpreted through business success; the museum notes that such a form need not mean the deceased actually owned the vehicle. A symbol can speak to status or aspiration as well as an inventory of possessions.
Purpose also matters. An object made for a museum has a different commission history from one made for a funeral, even when both draw on a shared sculptural vocabulary. Neither a bright painted surface nor the label coffin tells you whether an object has ever been used for burial. Follow the individual record instead of supplying an imagined personal story.
