Lovely Rita Shelving
I think this shelf would look really hot on any wall. I can imagine that it will look like a work of art when its loaded with books.
It can be used as a single shelf or can be repeated endlessly by combining a number of them, becoming a bookcase of the desired length. Its special shape also allows two different figures to be placed on the wall, according to the direction of fixing.
