These cute little ceramic/porcelain pieces belonged to my Mother-In-Law who passed away in 1999.  They have been in a cabinet or curio cabinet in my own house for all these years.  The need a good cleaning.  They all are hollow pieces and all marked with a black stamp MADE IN JAPAN.  They are very unique with them having big ears and long snouts.  I haven't been able to find any like this in all my research.  The momma pig measures 2 inches wide x 1 5/8 inches tall x 1 1/2 inches thick.  The medium piglet measures 1 1/4 inches long x 1 inch tall x 7/8 inches thick.  The baby piglet measures 13/16 inches long x 5/8 inches tall x  5/8 inches thick.  All 3 pieces are in great condition...no chips, cracks, crazing to the glaze...NOTHING.
