I am not entirely sure how old this tile is or where it was produced, I just found/find it very excellent, and wish I had a hundred of them, or maybe more! Made of cement, with some age to it for sure, and a real richness to that gray and black. (I find the matte surface of smoothed cement so beautiful to begin with.) I'd just prop it or set it somewhere and love looking at it like a painting.

 7 7/8" x 7 7/8". Very good condition, with a little roughness around the corners and a  light surface wear/a few scuffs.
