1965 - Delta Airlines Passenger Information Guide - Delta Airlines History and Memorabilia:

Up until the early 1970s, airlines such as Delta distributed flight information kits to passengers. These kits were replaced as in-flight magazines came online. These kits featured items such as post cards, puzzles, route maps, general information, drink tickets, and destination information. Some even featured foreign language translators and cards. This one features drink cards and luxurious reviews of the in-flight cuisine.
