Speaking of the GEO, their first convention will be held in Sheffield on March 10-11, 2023. There will be lots of Houdini representation with lectures by Chris Gower and Ann Beedham, author of Randini: The Man Who Helped Houdini. Tickets can be purchased at the David De-Val website. You can get more information at the GEO Facebook group.
Thanks Allan for the share!
