A backing material (1) is resistant to variations in heat, temperature and in moisture. Further, the backing material (1) is large in bending strength, tearing strength and in resiliency. Still further, the backing material (1) is relatively thin in thickness and light in weight, is tough, and is under tension so as to be resistant to curling and warping deformation. A worker may cut the backing material using ordinary scissors, knives and like ordinary cutting tools. Even an amateur worker may easily treat the backing material in a mirror-finishing operation of a photograph. Disposed on a photograph bonding surface of the backing material (1) are an immense number of deposits of an adhesive (2). These deposits assume dot-like shapes or linear shapes, and are provided at appropriate intervals. Alternatively, the photograph bonding surface is dense with geometrical microscopic irregularities or microscopic through-holes being filled with an adhesive. A photograph (3) is bonded to the photograph bonding surface of the backing material (1).
