Probably futile search as designs for wallpaper change regularly over 10 years. Try looking for pattern that brings the same feeling to mind. Lots of wallpaper options now online including British options.

It’s hand-painted wallpaper. Beautiful home:

I think you're in love with the scale, the airiness, the look of the whole space. Consider a local artist, and a similar hand painted effect directly on your walls. : )

A contact to Phoebe Howard, renowned for the look $$$$$$

It IS Snowtree by Colefax and Howard as Celery linked.

"When Nancy Lancaster, the 20th century tastemaker credited with creating the English country-house look, visited a ballet in Sweden, she was struck by a snow-white flower pattern on the prima ballerina’s dressing room wall at the Drottningholm Court theater.

Because Lancaster was in the same social set as the King of Sweden, he later sent her a gift of the pattern she so adored. She asked her decorator, John Fowler, to reproduce it for her home, Haseley Court, in 1954. That pattern, called Snow Tree, became one of the most enduring patterns for Colefax & Fowler, the design company she bought from Dame Colefax in 1944 and helped locate in Mayfair. "

Wow, gorgeous paper. And still sold by C & F, available in 17 colorways. Not inexpensive--sells for about $180 a single roll.

Agree gorgeous. But whenever you fall in love with something, it is often a thing that simply needs translation to YOUR OWN space. It's but one element in the inspo . Many ways to achieve the lovely feel in the room. The reason we call them inspiration pics, right?

We usually find we can love an interpretation suiting both room and budget :)

And sometimes we fall in love with an element, search for it and build our room around it. Why settle for an "interpretation" when you can have the object of your search? (Unless, of course, it's out of one's budget).

It looks similar to what I painted on my bedroom wall when I was about 15 and loved everything Japanese I think you could do the same or hire someone. $180.00 a roll is pretty expensive . I guess maybe post where you want to use it too. I agree with Jan that a inspiration pic id often a great jumping off spot to give a space your own look.

HOW MANY ?? times do we fall in love with something out of reach? From what I see here? A lot: !!

Before you get too stuck, get a pro paper hanger in there, a really good one. He will estimate his "drops" /cuts....and the rolls you need. Most often priced as single, and sold only in double rolls. Rule? NEVER order any paper without doing this_ I certainly would not. No matter the sticker price.

To me, It's a paper that needs a decent ceiling height, if only due to pattern repeat, : )

Is it refreshing that someone wants to design a room that does not include gray walls, gray rugs and too big black furniture? So, this particular wall paper is expensive...check with other wall paper brands for similar patterns. Please note all the other design decisions in the photos of this room. The look of the room is a result of all the design decisions not just the wallpaper.

Thanks everyone for your comments, and info. Much appreciated.

Here's a less expensive lookalike in lots of colorways. This look is so pretty! Actually, now that I'm looking, Ballard has several really pretty papers. They've upped their game!

Why is everyone assuming the OP cannot afford this paper? She asked for help i.d.ing it and people helped her find it - she didn't ask for help finding less expensive options. I'm glad it was found for her and if she decides to use it, I hope will post pics!

Olychick, I'm not sure that's the case. She asked for that paper or "anything like it" so folks are just trying to help. I posted the Ballard one because a couple of weeks ago on their podcast, they mentioned the paper because it looks like de Gournay. I would love to see how she uses it too!

stiley, I guess I missed where she asked for help finding anything like it. I see she wrote "anything on it." Ballard DOES have pretty options! Anyway, I'm glad she found what she was looking for.
