Abstract: A photo holder is described which can be smoothly applied to a page in a photo album. The photo holder has a peripheral border that nests inside the opening of a retainer frame while a peripheral holding edge fits beneath the frame. In one embodiment the photo holder is formed of a photo mat that is mounted on a backup sheet. The backup sheet is shaped and sized to extend past the photo mat to form the peripheral holding edge with angled sides that converge at a corner to form the protruding region. The photo mat is sized to nest inside the retainer frame. Various embodiments are shown and described including a photo holder with sides so cut that these form corners to facilitate insertion below the edge of the retainer frame.
