Abstract: The mount is formed by at least two sheets of transparent plastic material and an optional opaque intermediate sheet, all of quadrilateral shape, with bevelled corners, fixed to each other along part of their perimeter so that they form one or two back-to-back pockets of such a size that they hold with a sufficient margin a photograph with either a horizontal or a vertical disposition, the said pocket or pockets being provided for this purpose with apertures on two consecutive sides, through which the photographs can be inserted into the mount with the necessary orientation to enable them to be correctly viewed from a fixed observation point without the necessity of rotating the mount. The mount is provided with internal welds which ensure correct centering and retention of the photographs in the mount, regardless of their orientation. The opaque intermediate sheet is preferably of any suitable colour contrasting with the photographs and has a rough surface to keep the photographs in place.
