IDK, here is the blog that the image came from, posted in 2011. If the Portugese-speaking blogger is still around, maybe she can tell you where she got it. http://citrusandorange.blogspot.com/2011_09_01_archive.html

Here it is, but discontinued: [Zofanny Cordoba Wallpaper[(https://www.houzz.com/products/zoffany-wall-covering-cordoba-toro7002-discontinued-prvw-vr~25107882)

Replacement cost coverage on contents means that the insurance company may repair or replace the item in the event of a loss. If you had to replace the item, you would receive the amount of money required to buy a new item. Actual cash value coverage means that you are covered for the value of the item less depreciation. This is a very limited form of coverage. Make sure and ask your insurance agent or broker what the basis of claims settlement is on your insurance coverage for your personal belongings. If it is actual cash value, you may want to ask for a quote for replacement cost insurance. Your best bet is to call a high end paper installer. Then assume, IF you could find the same paper and you prpbably won't, but let us assume a very similar, untrimmed, hand painted, and the amount you would need. Let us assume it is priced as a SINGLE roll, and packaged and sold as a double roll. Because this is the issue with paper. There are "drops", pattern matches, and there can be , depending repeat, a very significant amount of waste. Which means even if you found it, you would need a total do over as the dye lot would be very different, and the age of the paper not replaced would be truly glaring. Thus you say, IF I found it, and it was 250.00 per single roll, with a comparable repeat, and you installed it........................what am I looking at? In dollars. And you present a signed document to the insurance company. Courtesy of a very reliable installer. Are some 100 year old patterns still "alive?" Yes, more likely in fabric, than in wallpaper. We often wish we could stop the hand of time. But a visit to any of the infamous luxury sources will show that the hand of time kept moving. De Gournay, Cole and Son, Scalamandre, Cowtan and Tout, Brunscwig, Schumacher all. Many more as well. This probably saddens Mario Buatta more than anyone. But for an insurance claim, you need the dollar info, of at least the similar in quantity, price of the goods, and installed in your home. Be prepared for some negotiation......: )

Looks like fabric to me, not wallpaper. Although, I really like that first one linked in the comments.
