Here we have a Schumann Bavaria round ceramic dish
I have researched for a couple of days and cannot find this patern, however it is similair to
Pattern: 19289 by SCHUMANN/BAVARIA [SCH19289] , but it has added designs.
Its approx. width is 4 1/2". There is a very small chipped off place on the very bottom the sits on table. But still a incredible find.
