Ideas for how to make a cleanable, removable 2D background for enclosure?

My plans for this are postponed since Pancake is recovering from surgery, but her enclosure is very boring and I wanted to do the thing where you build rock structures from foam and grout.

I see a lot of people build it into the background, but I have a wood zen habitats enclosure that was pretty expensive so I don't want to make any irreversible changes. The rock stuff is going to be removable, and I want the background to be removable too.

Any ideas for how to go about this? Her old glass enclosure had a cling-on backdrop of a desert, which you can see in my profile picture. I really liked that one but it's too small for a 120 gal. I'm looking for something similar. Right now the only idea I have is to maybe design a 4 foot by 2 foot background and somehow get it printed and laminated, then tape it in?

Wishing Pancake well. @xp29 can you help as you are awesome with enclosures but I am not sure if this is your area? Actually, I believe in you...you can figure this out.
