I have this wallpaper in my daughters nursery. The brand is Osborne & Little. The pattern is Benvarden. I ordered it via Miller Paint Store (Portland, OR), but they have a website that may have additional info.

Thank you so much for your interest in my work. I know it’s been awhile since you posted this question, and for that I apologize. As you can imagine, I get quite a few questions on Houzz; I’m afraid this one just got away from me. If you are still interested in learning the answer to your question please let me know and I will do my best to find it for you.

Best of luck with all your projects!
