Abstract: A construction for mounting adhesively backed pictures or the like comprising a mounting board and an oversheet detachably secured to said mounting board, said oversheet being positionable in overlying registration with said mounting board, said oversheet including guide marks thereon for the accurate positioning of the picture on the oversheet and mounting board, said oversheet being removable from the mounting board, independently of the picture, subsequent to an accurate positioning of the picture on the mounting board.

Abstract: A mount for mounting pictures and the like in accurate position including a base with a layer of adhesive on one or both surfaces and with a sectional release sheet overlying the adhesive, the release sheet material being sufficiently thick where a section is removed so that one or more sections can be removed and the picture to be mounted can be moved about on the remainder of the release sheet without adhesively contacting the exposed adhesive until the picture is accurately positioned on the mount, at which time the picture is pressed into contact with the exposed adhesive, and the remainder of the release sheet is removed and the picture is progressively pressed into adhesive contact with the remainder of the adhesive in a direction away from the previously exposed adhesive to provide a wrinkle-free bubble-free bond.
