Each frame is arranged for use with a standard-sized photographic print. The one or more frame includes a front wall with an opening to expose the photographic print and has planar side walls along the periphery of the front wall and extending rearward from the front wall. Recesses obscured by the front wall are provided in the side walls for receiving a connection means for securing adjacent frames together.
