Sid Dickens Memory Blocks: While some of these hand-crafted plaster tiles, 6" x 8" x 1 1/4", are finished to a porcelain like quality, others are cracked with the look of weathered stone to create an aged look and feel. Each Memory Block incorporates a unique chunk of history in a very modern way. Memory Blocks are best displayed in wall-mounted groupings. They are easy to hang. No additional supports, braces or mounts are necessary.
