This is the outer folder with slots inside for tickets and other pamphlets.... measures 13 1/2" x 10" when unfolded. There are a few creases but no real rips or tears. As I understand it the first DC6 commercial airliners took to the air in 1946 so from the blurb in the this booklet I would think this dates to about t 1946-47.
Rather rare item.
