Commemorative Postmark: Aomori Stamps have been collected and stored by two generations of a family. Due to advanced age, we have decided to pass them on to someone interested. They are stored in a stamp stockbook but have been kept at home for a long time. While they appear to be in good condition, please understand that there may be discoloration due to age-related deterioration. We believe the condition is good, but please judge from the images. Please refrain from purchasing if you are seeking perfect condition or are overly sensitive. We plan to ship via anonymous delivery using YuYu Mercari便. If soft packing materials are used, we will take measures to prevent the contents from bending during delivery. We also have other stamp-related items listed, so please take a look. Discounts will be offered for combined purchases.
