The wallpaper is called Frenemy Midsummer and according to the company that produces it, BOBO 1325, it is inspired by Joy Division's 'Love Will Tear Us Apart'. This is the description from the promo material I saw:
"A human being has the capacity to be their own best friend and their own worst enemy with the blink of an eye. We are both Saint and Sinner. Jury and Executioner.
"Frenemy explores the depths of the human psyche and social conscience. The delicate tones for the days we feel Saintly whilst the darker shades depict the darker side of humanity. Come with me and walk the fine line between pleasure and pain of love, life and friendships with a certain sense of ethereal fluidity juxtaposed with strong black."
Anyway, I couldn't resist sharing the image. The company does some great fabric too....
