My thought behind the cover is that the viewer is searching "flak" puzzled by this word. The definition of the word is shown like it would be if it was actually searched on Google. This will evoke a very broad and general understanding of the overall theme. Hopefully pushing the viewer to open it up to reveal more.
Once the viewer opens the specimen, the glyphs are shown as a sort of digital slag meaning "wtf?" is "flak?" (Probably what someone looking at this for the first time would be thinking.) So underneath that is the description of the typeface which reads: "Flak is a display typeface that embraces digital imperfection. Condemned by the traditionalist and celebrated by the rebels. This typeface adorns the glitch in the system and applauds the criticized, radical, and forward-thinkers." This also shows all the uppercase characters.

Now that the viewer has a pretty good understanding of the typeface, I wanted the full back side to be functional as a poster.
The back side shows all the lower case characters, that mirror the upper case when unfolded. Because the front panel is so abstract, I wanted to give a little sample of the typeface itself on the "outside cover" so they would know it's a type specimen. It also has a place for the postal stamp and three blank lines for addressing.
