The vermilion border is a common feature of postage stamps from around the world, but it is most commonly associated with stamps from the United States. The United States Postal Service (USPS) began using the vermilion border on definitive stamps in 1879, and it has continued to use it ever since. The USPS has also used the vermilion border on other types of stamps, such as commemorative stamps and airmail stamps.
The vermilion border is not only a practical design element, but it is also a part of postal history. The vermilion border has been a part of postage stamps for over 100 years, and it is an enduring symbol of the postal service.
