Bavaria Schumann Plate with scalloped edges

This is a large dinner plate with one arrangement of flowers in the center of the plate. The edge has gold, rectangular like designs containing smaller flower arrangements. The scalloped edge is lined in gold. The mark on the back is a shield containing a lion. Bavaria is written above the image and Schumann is below the image. Just above and to the left of Bavaria is the number 64. At least that's what it looks like.
