I went along to this earlier in the year
https://www.senatehouselibrary.ac.uk/exhibitions-and-events/exhibitions/staging-magicJust a heads up to anyone planning to visit - the private security were adamant that non-id card holders could not go into the Library - even though it is billed (and is) a public exhibition.
Managed to get in (along with a couple of others who were also being turned away at the gate.
Have to say bearing in mind the library holds a colossal collection - over 13000 items in the Harry Price Collection of Magic the exhibition was tiny and uninspiring.
My score? Could do better!
