I was walking down a street in my town, and found this cool, but old, sidewalk where the owner had decorated it with cool patterns made from old discarded pieces of Granite kitchen countertops and cement. It was in bad shape, which shows that it has been there for years, most likely decades. The shape of the granite pieces also tells me these were discarded from a factory that made granite furniture for kitchens and such things, my guess is the sidewalk was made in the 1970s.
