Our Snow White textured Standard A3 picture window mounts have a centrally positioned aperture in order to suit both portrait and landscape images, allowing approximately 10mm all round to attach your image to the back of the mount. The acid free board from which they are cut is an off white, neutral shade board with a white core and is a framing industry standard.
