These were made to quality specifications and that stands out to this day. Fine quality thin porcelain. Someone enjoyed them a good deal as there is some wear to the artwork on the cups. They took good care though, no chips or cracks although I didn't take a microscope to them. Floral marking on the insides of the cups, otherwise no markings at all on the bottoms. I am not certain of the age but I would not be surprised if they are very old. Background color is a nice bright white, if a photo looks otherwise blame my webcam.
