An artist's book in a limited, numbered and signed edition of 500 copies. The house identical to mine, my neighbours' house, had the peculiarity of being its mirror: everything in it was reversed. If our kitchen was on the right, theirs was on the left, and so on through the whole house; as a child I thought it must be the same for thoughts, mine necessarily the reverse of theirs, a notion that was by turns hopelessly complicated or utterly simple, depending on how you looked at it.
