Before we take a closer look at Disneyland's early 1980's ticket exchange policy, let's review the current policy. Although the current policy is not publicized, today you can still exchange old tickets for entry to the park. I don't think the "point" system still exists (it might?) but I do know first hand that you can exchange complete books for a current park ticket, see my post here (link) as proof.
This sheet from the magical "ticket binder" begins to explain how the exchange program worked for Complete Ticket Books. Ironically these are the simpler exchanges, its gets much more completed as you will see in later posts of this series, by the way - I've got a lot of these, this is just the beginning.
Come back soon for part 3; More complete books! And since I've had two kind readers ask for Bonus Sunday it will return this weekend!
