This two-sided document was designed with panels oriented to face the correct direction when unfolded.

This first image is the outside of the folded mailer, with the top panel being the front cover, the middle panel being the back, and the bottom panel being the inside fold.

This document was designed to have the season pass, a face covering (buff), and stickers glue-dotted to the inside. 

These two images are identical, but left image shows the blank document with fold marks, the right image shows document with add-ins mocked up.

Whereas the outside layout involved changing orientation to account for folds, the inside of the booklet is meant to be viewed fully unfolded, so all three panels can be oriented top-up.
