The Benin artifacts previously delivered to Nigeria from UK and Germany have disappeared from public view. They are not on display in any museum. Some or all may have been sold into private markets. (Links in next tweet)
See here https://www.theatlantic.com/ma... and here https://www.theatlantic.com/id... Western museum curators know perfectly well what happens to art works delivered to Nigeria but are intimidated into silence.
The late PJ O'Rourke had a great line: "Just as some things are too strange for fiction, other things are too true for journalism." The fate of artworks delivered to Nigeria is one of those subjects too true for journalism. Fiction and fantasy are reported as moral imperative.
Some non-European countries have successful museum systems: Mexico and Egypt eg. Britain bequeathed Nigeria such a system at independence in 1960. That system was wrecked. There's no serious plan to restore it. It's no favor to anyone to pretend otherwise.
