Is it painted on the wall surface?

I have to ask, if he is OK with you hiding it, why not just paint or wallpaper over it.

I have to hide it behond something temporary, as he doesn't want it to be "gone"

It is a wallpaper mural. I thought some kind of taunt fabric or removable panels that snap in place? Something that won't damage the wallpaper behind it.

Room divider or books cases would probably work

I'd say tall book cases. Although this will decrease usable square foot space for floor. And that only works if you have lots of books or lots of knick knacks that work well together. Barring that, you may find panels that cover most of it up.

You could do wall to wall drapes on that wall. A wall of drapery creates a nice acoustic in the room.

You could also mount a rod at the top and the bottom of fabric, create a flat panel with a rod pocket at top and bottom and mount it. This sounds easy and seems like it would work, but if the width is anything beyond three feet, it will always be baggy. So, don't do it, even if you see it on Pintrest. :-)

Mounting panels of fabric on the wall will require holes in the wallpaper. I've researched this a lot as I have a wall I want to upholster with fabric. In the end, I've found no way to do it as one flat panel other than having pros come in and do this https://cleanedgesystem.com/ (they say it's DIY but I'm a very experienced DIYer and seamstress and it frightens me) or do a lot of panels that will damage the wallpaper like this: https://www.youtube.com/watch?v=S6LovADuyZ0 

Try a drapery wall in a neutral color or that coordinates with the wall color.

Post a picture of it, maybe we can help you see it with new eyes.

A wall of bookcases could be a useful and attractive solution, but as they have to be secured which would damage the wall, see link for option and instructions and I think framing and the moulding would secure them. Ikea’s Billy bookcases come with backing so wall will be hidden. If the measurements don’t work out width wise, you could frame sides as per the top. If you are not handy, I’m sure it wouldn’t cost a lot to hire someone. Sounds like you will be staying in your home, so may be worth adding something that is useful and attractive.

Could you try and capture it in a photo to have framed and hung somewhere in the house? Then you could paint over it and he still has the memory

Photos of the existing condition would help us help you. I think fabric on plywood panels would be easiest and reversible.

What is the size of the mural? That will help....

I think we need to see it. 😊

what about it don’t you like? How big is the wall?

You can use fabric, that is soaked in starch, to temporarily cover walls. The fabric can be pulled down without wall damage but I have no idea what would happen if you place it over wallpaper.

Take really good pictures of it and ask him if having the photos would be good enough for him to keep.

@HALLETT & Co., would love your advice on how to use plywood panels for this application. I have a wall I"m trying to cover that is 8' X 7". I can't find a panel that is that large and using two panels becomes unwieldy for me. Also, any tips on how to mount the panels with hidden mounting is appreciated. I have considered using channel rails at top bottom and sides. Truly, any tips you have are appreciated. I just can't figure this out.

Hi Pam! Is there any chance that the wallpaper mural could be removed intact (perhaps by an expert wallpaperer or even art restorer)? If so, it could be stored away, or perhaps itself mounted onto moveable screens if your husband wanted to use it in a room in the future. Good luck!

You want to use a panel no wider than 48" even if you could find larger- fabric is typically 54" wide. Make two panels half the width of the room. Use GOOD 1/2" plywood, cover it with thin batting and then staple the fabric on from the back pulling it taught. As for mounting it you could use small nails depending on where it is going, or a french cleat at the top, or a channel. Lots of ways to mount depending on the space and the wall material

This the mural. It is absolutely not my style, matches nothing color wise and just makes the entire room look old and dated. It is 70's colors like orange and yellow-gold army green. It has probably been there since the 70's. They were both in thier 90's, so it has been there for a very long time. It covers almost the entire long wall where the couch needs to go, and it does not match. I just don't feel comfortable in my own livingroom staring at it day after

I don't have a tape measure handy, but it is 4 panels of wallpaper and wider than a 90" sofa. There is an additional plain panel on either side plus a door opening to the kitchen.

Goodness. I don't blame you at all, and just wanted to say that I sympathize with you. I wouldn't want to look at that thing either. It's nothing special, except to your hubby's sentimental side. I guess I gotta give him props for having a soft spot for it, but man ... I feel your pain in wishing it out of sight! Good luck; I'm sure you'll think of something that will work for you both.

Not a pro. Maybe try peel and stick wallpaper? If you do something patterned or darker, it could work to hide it.

@partim, have you ever done this process? If so, how did it go? Any tips?

@HALLETT & Co. thanks!

With many of our things we just photographed the person with their thing. You still have the memory but can move on with your current lives, and review the memory anytime.

Get a rail hanging system, install it at the very top and put up a large triptych. You can put the pieces very close together and you won't notice the mural.

No I have never done it.

Panel system

You are a very good wife. How about a panel system like this - works like draperies but a bit more sleek.

Thanks for posting the photo. That would be hard to work around when decorating.

Since every house needs some whimsy, I would probably add little creatures to it. Maybe a bird in the tower and puppy near the gate to see if my DH noticed.

Good luck.

I found these hanging panels from Inhabit when I was looking for wall panels and they might work because they don’t attach to the wall and therefore won’t damage the mural wallpaper. In the photos they are used as room dividers but I assume they can be hung in front of the wall easily.

They have 3D designs, are modular, and come in colors in felt or paintable in a paper fiber/resin. Probably not the cheapest option...

I know I’m probably too late to help with the suggestions but maybe someone else will find them by checking out your post!

Oh yikes! If you’re still struggling with this I would take everything away from that wall, ask a photographer friend to take a great photo of it and paint it while he’s gone 😉. He’ll have the photo to preserve his memory of it. I don’t envy your having to deal with that emotional attachment to bad design.
