This fine harp would appear to be by the same carver as various artefacts in the American Museum of Natural History, New York, collected in 1910 by the American mammalogist Herbert Lang, e.g. a figure, a knife handle and another harp (Schildkrout and Keim, 1990, p.132, fig. 7.15, p.136, fig.7.21 and p.201, fig.10.10): in Lang's field notes he records that the blade of the knife was made by Chief Okondo's blacksmith and another man carved the anthropomorphic handle. The carver may be Gataye, who signed a box in the Musée royal de l'afrique centrale, Tervuren (op. cit. p.245, fig.12.10).
