A holder for protectively displaying flat collectible items such as sports cards and photographs is made of a jacket and an insert member shaped to slide into and closely fit within the jacket. The insert member, fabricated of opaque sheet material, contains a centered rectangular aperture which accommodates a flat collectible item. The jacket is constructed from two identical sheets of semi-rigid non-breakable transparent plastic bounded by four straight edges in a rectangular configuration, and bonded together at three edges.
