EVERYTHING ABOUT THIS COVERED BUTTER DISH PROCLAIMS BEAUTY AND ATTENTION TO FINE DETAIL.  EVERY PART OF IT WAS CAREFULLY PLANNED AND CRERATED TO PROVIDE YOU WITH AN HEIRLOOM QUALITY ACCESSORY THAT YOU WILL CHERISH FOR YEARS TO COME.  BUT THE TERM "COVERED BUTTER DISH" IS FAR TOO RESTRICTIVE FOE THIS LOVELY PIECE.  BESIDES HOLDING HOLDING BUTTER, CONSIDER A CHEESE BALL, STEAK BUTTER, MOLDED PATE, CUBES OF CHEESE, OR FUDGE, SMALL COOKIES AND MORE.  THE COVERED DISH IS A DEEP COBALT BLUE GLASS.  MADE IN THE USA.  IT HAS THE LEAF-GRAPE PATTERN.  AGE AND MAKER UNKNOWN.  I WOULD GUESS INDIANA GLASS BUT NOT SURE.  THE DISH HAS A SCRATCH ON THE INSIDE BOTTOM.  OTHERWISE IN EXCELLENT CONDITION.
