Although we would love to celebrate with all Houdini enthusiasts from across the world, achieving the high standards we envision for The Grand Houdini Centenary within our physical constraints is a challenge. While most planned public events will be open to all friends of Harry Houdini, the infrastructure of The House of Houdini, our partner restaurants, and The Gundel can only accommodate a limited number of guests. We promise to respond to your invitation request as soon as possible, hopefully with a confirmation and further details. Thank you for your understanding.
