Tickets to
the Museum are printed with white
ink on indigo-blue cardboard stubs. On one side is printed the box title
"The Museum", and a depiction of an armillary sphere with a spiral
galaxy within; on the other side are instructions on how to reach any of
the six gateways, framed in a box with the name of the ticket's
recipient. Often,
Mel first learns a person's name by

Despite the formality of these personalized invites, anyone is allowed
to enter the Museum even if they do not have a ticket. Acceptance of a
ticket confirms the holder's acceptance of the Museum's physics while
within its halls (see "Physics of the Museum Proper" on
its page; discarding a ticket constitutes
refusal of these same physical attributes.
