This looks like de Gournay or Gracie, which are hand printed or hand painted papers. I don't want to assume anything about your budget, but this is an expensive paper. I priced a less expensive paper than de Gournay in a non-repeating scenic and it was about $1000 a panel (ten ft height, not eight). Less expensive but similar is Schumacher's Madame de Pompadour https://www.fschumacher.com/Item/5008542 Just as an aside, I think this paper is relatively wasted above. I can't get past the chrome escutcheons, flex line and plumbing cleanout access under the vanity.

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, : )
