Poseidonia M2503-1 is a Tres Tintas wall mural from the Méditerranéen collection, designed by Lázaro Rosa-Violán, in blue and grey. Long, blade-like leaves rising from the foot of the wall, printed in broad dry-brush strokes at a large scale.

The name is that of Posidonia, the seagrass of the Mediterranean seabed, whose long blades the design shows. The strokes are large, so it reads as one strong gesture. Made in Barcelona and printed to order.
