I think I prefer the British Museum set, but that's because I see most of the best things in the Met set (the hilarious Book of the Dead translations, the ink cakes) every few months. Highlights: the Japan-Manchukuo Fraternity Board Game and Pieter van Laer's "Magic Scene with Self-portrait", which I'm glad I photographed in 2008 because I'm pretty sure the Met rotated it back into long-term storage.
There's at least one set of sculptures split between the museums: look in the background here and then here.
Tue Dec 29 2009 10:19 Today's Pictures: Museum Showdown:
No 2009 gallery today. Instead, it's a transatlantic museum showdown. In which museum was I able to take more cool pictures in 2008, the British Museum or the Metropolitan Museum of Art? Which museum-filling technique yields better artifacts: imperialist exploitation or robber-baron bequests? Whose cuisine will reign supreme?
