Been to see it today. It's a small exhibit but it's good to see some itmes that aren't normally on display at the British Museum (ledger drawings collected by Blacmore, for example). The additonal stuff is a bit of a mess. Some interesting items, some hobbyist/enthusiast reconstuctions and a half-hearted attempt to say something about the use of images of Indians that falls flat due to lack of context and the need for more content. One day, somebody will organise a good touring exhibition based around the items in British museums other than the British Museum itself... There's plenty of stuff out there and I imagine there's a lot more that never gets displayed.
