This is a Reinhold Schlegelmil porcelain hand painted scalloped cupped small bowl with an interior mother of pearl glaze. The exterior is hand painted with small blue and white flowers. I think the hand painted decoration was done by an amateur. The base has the faded green authentic RS Germany mark that was used from 1912-1945. It also has a hand painted gold signature of the artist, which I can't quite make out. It might read Minerva or Minnie. The bowl is 5" wide and 2 1/4" tall. It is in excellent condition with no chips or cracks. MBR.
