Prosa RU3405-4 is a Tres Tintas wallpaper from the Rúbrica collection, in black and white. Long narrow leaves, curving stems and comb-like fronds, overlapping in a dense tangle drawn with grainy, uneven strokes.

Prosa is Spanish for prose. The leaves fill the ground edge to edge, so it reads as dense foliage from across a room, and the grain of the strokes shows up close. Made in Barcelona and printed to order.
