The backing seems very hearty on these. Heavy duty and tough.The good review ends there.I have 3 problems with these.First, the colors are very muddied and muted. Not at all what Vincent had in mind. So they aren't that wonderful to look at.Second, they are blurry, out of focus. I get that a 3' painting was blown up to a 12' one, but I think the blurriness goes far beyond thatSo they just aren't pleasant to look at.And finally, the 6 strips making up they picture are not made to butt together. They overlap by about 1/8".This makes installation (which I am not going to do, since I don't really like the pictures very much due to reasons 1 and 2 above) as very close attention is required during install. And the picture wouldn't be flat, since there are strips of double thicknesses on the wall.Sorry i bought them.I was excited, but save some money and grief, the pictures aren't worth looking at I am afraid.....Comes in sheets that must be hung like wallpaper. I wouldn't have pruchased had I known this. Once hung (an exhausting progress) it looks good enough. Rehanging would require finding a wax backing to apply to the adhesive while moving.Just received this today, and decided to put it up the same night. When I first took it out of the box, I thought to myself that the image was kinda grainy and it wasn't going to turn out well. Put up all 6 pieces by myself, fairly easy. Turned out beautifully, I would recommend this to my friends!I bought this for my Granddaughter because she is an artist. It was beautiful for 3 days. It then fell and was like a ball of duck tape. I contacted the sellers. No reply. I just asked for another one and had intended on using very small brads to secure it. To this day I haven’t heard back from them. Super dissatisfied with the customer service as well as the adhesive on their product.I love this. My friend and I put this up in my office. It didn't take that long. It does need wallpaper paste to permanently stick. It'll really bring the room together when my office is finally finished.This was the easiest, most dramatic, wonderful, beautiful thing I have ever done. It is great and I recommend it if you want something different and unique.Looks wonderful
