White vs. Gray Exposed vs. Concealed

Hello, all. Brody asked me to post these altered images for your consideration and input. There are few proposed options how to address this wall:
- Option one: Expose the actual construction process: seams, no paint, only front side covered with dry wall, top part could be left open or again covered with gray dry wall.
Reasoning: To show that this is a" pretend wall", to show process and additional benefit the actual gallery wall will not be destroyed and disassembling will be easier.
- Option two: make it perfect as possible replication of dry wal, paint white to blend in with the rest of gallery ( back side could be covered or exposed to emphasize the faux feel).
- Option three: Cover the part of fake wall ( not the existing side walls) with different material (paper, plastic, nylon, etc) - again to bring up attention to the fakeness , signall the intent , mark the threshold..
Thats all. Brody please, add up if i missed something.
