These have their own mystique. The history on these cards is a bit vague. But apparently, these were handed out to all kinds of Delta employees to hand to kids on the flight. Delta printed a ton of them, but as they were handed out to kids, not a lot of them survived. They were printed in the late 80s and 90s, but not much else is known. I was given a set when we went on a flight in the 90s. Wish I still had those.
