has been considered emblematic of the repatriation of the African continent. The artefacts have become a test case in the international debate over restitution, comparable to that of the Elgin Marbles. The British Museum sold more than 30 Benin Bronzes to the Nigerian government between 1950 and 1972. In 1950, the museum's curator Hermann Braunholtz declared that, although made individually, of the 203 plaques acquired by the Museum in 1898, 30 were duplicates; because they were identical representations, he determined that they were superfluous for the museum and were sold. The sales stopped in 1972 and the museum's African art specialist said that they regretted the sales. A newspaper publication revealed that in 1953, Sotheby's sold a Benin Bronze head for £5,500 when the previous record sale was £780. In 1968, Christies sold for £21,000 a Benin Head that was discovered by an officer around his neighbour's greenhouse. In 1984, Sotheby's auctioned a plaque depicting a musician; its value was estimated at between £25,000 and £35,000 in the auction catalogue. In 2015, a Benin Bronze head was sold to a private collector for a record fee of £10 million. In 2018, an agreement was made between the Benin Dialogue Group (BDG) and the government in London to return Benin Bronzes that will be used to form a temporary exhibition at the New Benin Royal Museum in Edo State. The group comprises representatives of several international museums, the Royal Court of Benin, Edo State Government and the Nigerian National Commission for Museums and Monuments. In 2015, Mark Walker returned some Benin Bronzes that were taken by his grandfather during the siege on Benin Kingdom, and he was received by Prince Edun Akenzua in Benin City. In 2020, Nigeria took receipt of a terracotta head that was believed to be around 600 years old, which had been smuggled out of Nigeria. The University of Aberdeen agreed in March 2021 to return a bronze head of an oba, that had been purchased at an auction in 1957. In April 2021, the German government declared the restitution of "looted" Benin bronzes in Germany's public collections by 2022. Hartmut Dorgerloh, the director of the Humboldt Forum, which incorporates the Ethnological Museum of Berlin, said at a press event that exhibiting the Benin bronzes in the new museum complex in Berlin as earlier planned is "now not imaginable". Also in April 2021, the Church of England
