Not sure if this is the best place to put this?
For anyone living in, or passing through London, just to draw your attention to a free exhibition currently on at the British Museum. It's roughly arranged around the theme of the Triratna or Three Jewels of Buddha, Dharma and Sangha. And while it's not the best curated exhibition I've ever seen, it does contain a few very good rupas and other items. In particular there is a quite remarkable metal rupa of Dolpopa Sherab Gyaltsen to be found in the sangha section.
