At the event there will be autograph sessions with all the guests which will be managed by your ticket type and number. There will be the chance to obtain autographs even if your ticket does not include autographs, a charge will be applied.
Autographs will include an item to be signed on, but you are welcome to bring an item from your own collection to be signed.
Tickets for autographs can only be purchased on the day, and not in advance, once you are in the queue for the guest.
