A card or sheet cover has a center fold defining a first foldline dividing the cover into front and back panels. The front panel has a section formed by a second foldline parallel to and spaced from the first foldline, such section overlying a corresponding section of the back panel such that the front and back panel sections together define a portion of the cover capable of being grasped for attaching the cover to a support while permitting the front panel, outside its second foldline, to be flipped open to gain access to the underlying card or sheet which is retained on the inner surface of the back panel by a shallow pocket or the like.
