Museum Island Objects

Prompted by the "Natural History Museum's":http://www.nhm.ac.uk/ attempt to "do away with":http://www.bbc.co.uk/news/science-environment-31025229 Dippy the (fake) Dinosaur (quite rightly), I wondered why some museums are automatically associated with a single object, and others aren't. My attempt to record this:

| Museum | Object | Notes | | :----- | :-----: | :-----: | | British Museum | Rosetta Stone | or Elgin Marbles ? | | National Gallery | Sunflowers | Certainly makes them loads of money in their shop | | National Portrait Gallery | ? | Hard to say. Chandos Shakespeare ? | | Natural History Museum | Dippy | Doomed! | | Science Museum | ? | Oddly enough, nothing really springs to mind. Babbage's difference engine possibly but it is too recent | | Victoria & Albert | ? | Perhaps so much variety it's hard to compress down to one object ? | | Imperial War Museum | The guns outside | And the medal gallery |

More to be added.
