A Collector Ticket is a souvenir, 3D style ticket which admits the holder to the event and serves as a treasured keepsake to be kept well after the event.
Collector tickets are only made available for selected events and can be purchased through the normal purchase processes - just be sure to select a "Collector Ticket" specifically when choosing your ticket type.
Collector tickets can only be delivered to fans via mail, and cannot be sent as Print-at-Home or E-Tickets, or collected from outlets or the venue.
