These items were at my in-laws' house. The two plates in the first half of the photos and the two plates in the second half (pansies and irises) have different back stamps, but I believe they are from the same series. I cleaned them with oxygen bleach. The ring-like stains visible on the back of the two plates in the second half when held at an angle could not be removed. Also, "crazing," which is characteristic of ceramics, can be seen. I would like to offer these to someone who understands the above. Shipping will only be on weekdays; it is not available on weekends or holidays. Material: Porcelain/Ceramic Shape: Round plate
