ABSTRACT OF THE DISCLOSURE A photographic album page comprising a fibrous centrally diposed lamina and a pair of overlying clear synthetic resinous laminae.

The pockets are thus formed as a continuous sealing operation at the same time the page is laminated by sealing in broken lines, whereby the fibrous lamina retains its structural integrity.
