For those not involved in the art scene, the infamous, anonymous street artist known as Banksy opened up a hotel with an art focus a few years ago called the “Walled Off Hotel”… A take on the Waldorf hotel. He had local sculptors create small pieces of the retaining wall for sale to bring money to the region. These little mini wall sculpture pieces are highly collectible and very valuable. Especially the bigger wall sections like the ones picture here.
