This magnificent mosaic, located in the middle of the Las Ramblas, conceived by the artist as a welcome to the visitants that arrive to the city from the sea along with two others who welcomed the visitors who came from the land (“Dona i ocell” Parc de l’Escorxador, near to the main train station) and from the sky (Mural in Airport, terminal 2).

This ring, made in 1976, intents to be perceived as a big cosmos with the basic colors: red, blue, white and yellow and it shows the whole spirit of this artist.

The name of the work is due to the exact place where it is located: in the “Pla de l’Os” that means “space of bone” in English. This was the place where the lazy people without steady work hung out. The locals, to avoid calling them lazy people, said they had “os a l’esquena” (a bone in their back) which prevented them to go to work.
