The photograph album has front and rear walls in one piece and joined by a fold, and also at the sides. Two strips integral with the front wall(2) fold inwards along its side edges(3,4), and are glued to the rear wall(1) at a distance(A) from these edges equal to more than half the maximum height of the stack of photographs to be accommodated, and less than three times this height. The gluing positions(8,9) are set back from the album bottom edge(5) for a distance(B) likewise equal to between one half and three times this height. ADVANTAGE - Simplicity, low cost, and low stacking height when empty.
