Q: I’m the owner/operator of the Disneyland Postcard Reference Guide website, and I am trying to create an up-to-date checklist of Disneyland postcards published starting from when the second edition of The Nickel Tour left off. I’m sure I have all the postcards but failed to record when I purchased them. Is there a way to check what postcards were produced, and when? Also, is there a way to check the number on the back of a card and cross-check it with a database to determine when it was published? Any information you can give me would be very helpful.
