I’m told that:

There will be an event in central London on Sunday 14th May to mark the death fifty years ago of Austin Osman Spare, and to celebrate his life and work. The event will include several talks, the auction of a unique book, some items for sale, and a small exhibition. All proceeds from this event will be donated to the R.S.P.C.A.

Further details of the event, its location and time, will be announced shortly.
