In a small antique bookshop in the streets of Barcelona, we found these beautiful facade drawings hidden away in a box. We couldn’t help but fall head over heels for these elegant and incredibly detailed hand-painted drawings. They were drawn by an architectural firm in Paris. How they ended up in Barcelona we don´t know, but now they can find a new home, in the shape of wallpapers with you. If you take a stroll down Rue Drouot or Rue Roissini in Paris you will pass at least one of the buildings. By Rebel Walls.
