Produced by Drucki & Lubecki before 1920 when the name of the factory was changed to Cmielow, it has such a very unusual and interesting porcelain surface covered with a spider web "cracks" while maintaining its integrity. Its dimensions match the U-1784 on the NIA website, but as a product from Drucki & Lubecki it is not cataloged there... yet. An interesting addition to the collection.
