THIS IS A CLASSIC VINTAGE PIECE, AND VERY WELL MADE.  IF IT HAS A MARKING, I CAN'T FIND IT.  BUT IT COULD BE A CALIFORNIA PIECE?  HAD A LABEL ON BACK, BUT MISSING.  WAS FOUND AT ESTATE SO SORRY DON'T KNOW ANYTHING ELSE.  THE TILES ARE 1/2" BY 1/2" WHITE SPECKLED IN LIGHT GRAY, AND A BABY SOFT PINK.  THERE ARE SOME OTHER TILES DIFFERENT IN SIZE AS YOU CAN SEE BLACK WITH A LIGHT FLECK, AND GRAY WITH A LIGHT FLECK.  ALSO A LIGHT AQUA WITH FLOWER DESIGNS IN IT.  THE BACK ALSO LOOKS LIKE IT IS A MOLDED COPPER.  VERY ELEGANT FOR DISPLAY WITH YOU COLLECTION. 
THANKS FOR LOOKING AND BIDDING.
