Pan American World Airways Poster? Booklet? Brochure? Read Description 62

Description

This was part of a recently purchased collection.  I am not sure if it was all one thing originally, or if it 2 different items.
First is the cover, which opens to sort of a poster kind of thing.  It has serious separations as shown and needs to be treated gingerly to prevent further damage.
Inside of it is a 16 page booklet with sample pages shown.  The first page looks like it is lacking something . . . note that there is part of a tail wing thingie at the upper left that connects to nothing.  Is it missing a cover and so was put inside the first item for safe keeping?
I will allow you experts to puzzle this item through and determine the value.
NOTE: We combine shipping whenever possible on auctions ending the same weekend.  If you purchase multiple items PLEASE wait for our invoice before making payment.
We
CANNOT
combine auctions covering multiple weekends; please don't ask. If this presents a problem then please do not bid on our items.
We do NOT and will NOT ship outside of North America.  If your plan is to win an item and then ask fhat it to be shipped elsewhere, that will NOT happen and sale will be cancelled.
Letter/number at end of auction title is our inventory number.
I do not find issue dates on either item.
Cover condition as shown; contents are fine.
Buyer pays .00 First Class S&H.  If shipping weight of combined timetable purchases exceeds the First Class weight limit we will ship Priority Mail at a flat rate of .00 for all timetables purchased.
When practical, we gladly combine shipping on auctions ending the same weekend to save you money.
Buyer satisfaction assured - Bid with confidence.
All items will be shipped in quality rigid mailers with extra stiffeners or a box for protection.  While I understand that shipping in a regular envelope reduces cost, experience has taught me that it is not worth the added chances of an item arriving damaged; please don't ask me to do it.
