One of Banksy’s murals at the West Bank Barrier, the Art Attack mural shows the sky peeking through a large hole in the wall. A Palestinian child is shown longing to go to the beach which the separation wall is depriving them from visiting. 

This is one of the many murals that depict similar themes at the West Bank Barrier, where different holes reveal different parts of the beach.
