I don’t know much about this except what little I could find online. Apparently it’s a cross stitch bombing in Valencia, Spain:
“Lope de Vega of Valencia Square is located in the heart of the city, between Plaza de la Reina and Plaza Redonda. Although it is small, has a significant flow of neighbors and especially tourists, they walk through the old town in groups. For several months, also it has a new attraction: a facade decorated with cross stitch.
It is the work of Raquel Rodrigo, Valencian designer, 30, who last November participated in the Festiva Intramurs. Her work decorated the facade of the store of a bar/restaurant, Ocho y Medio, in Lope de Vega square. And there it has remained since. Hundreds of tourists and locals pass by Lope de Vega square every day. And many of them are amazed at how unusual to find cross stitch decorating a wall.”
Oh, and here’s a video!
