The album page comprises a rigid sheet of fibrous-based material, rectangular in shape and used as a common backing. Two similar sized sheets of a thermally weldable transparent plastic material are also used, one being placed each side of the common backing. The transparent plastic material is fixed to the backing by means of an ultrasonic stitch welding, the effect passing through the backing to join both outher sheets together and form pockets. From one to four pockets are provided by varying the lines of ultrasonic welding.
