ABSTRACT:
A photo album held together by attachment assemblies, each including (1) a barrel part having an internally threaded tubular portion and a plate at one end that will not pass through the openings in the pages and attachment portions of covers for the album; and (2) a screw part comprising an externally threaded portion adapted to threadably engage the tubular portion, and a head at one end that also will not pass through the openings in the pages and the attachment portions. The plates have projections received in sockets in the attachment portion of the rear cover to restrict rotation of the barrel parts; and the heads on the screw parts have ridges along their peripheries and large diameters that afford easy manual engagement with them to engage or disengage the screw parts with respect to the barrel parts.
