Abstract
Abstract Photograph album leaf and method of making same. Leaf is sheet with heat sealable outer surface folded to form pages back-toback, spaced photoprint window pockets being peripherally sealed thereon. Slots underlying pockets provide access for inserting prints through reverse side of sheet between pages. Method includes steps of die cutting slots in flat sheet, overlaying transparent heat sealable sheet (preferably preprinted with decorative borders defining window pocket frames); sealing the pocket margins and simultaneously forming peripheral tear lines; peeling off overlay material around pockets; folding the sheet and forming a binding strip along marginal portions at the free end edges of the sheet.
