Abstract of the Disclosure A stack of sheet assemblies, each of which sheet assemblies comprises first and second sheets each having front and rear major surfaces and first and second opposite edges, a first layer of adhesive adhering a portion of the rear surface of the first sheet adjacent its first edge to the front surface of the second sheet adjacent its first edge with the first edges generally aligned, the first layer of adhesive extending a first predetermined distance from the first edges toward the second edges of the sheet, and a second layer of pressure sensitive adhesive on the rear surface of the second sheet. The second layer of pressure sensitive adhesive comprises a first portion adhering the rear surface of the second sheet of the sheet assembly to the front surface of the first sheet on the sheet assembly beneath it in the stack within the first distance from the first edge. The sheet assemblies also include release means for providing first adhesion zones between the front surfaces of the first sheets and the rear surfaces of the second sheets of the sheet assemblies in the stack, the first adhesion zones extending about the first predetermined distance from the first edges toward the second edges of the sheets and providing a release force between the first portions of the second layers of adhesive and the front surfaces of the adjacent first sheets in the stack which is lower than the release force of the first layers of adhesive to the first and second sheets to afford easy initiation of peeling of the uppermost sheet assembly from the adjacent sheet assembly in the stack along the first adhesion zone by pulling on the first sheet of the uppermost sheet assembly on the stack.
