US 1940~2000 First Day Cover Stamp/Envelope Collection

Product Name: Collection of First Day Cover Stamps/Envelopes in the United States from 1940 to 2000 Product desciption: Fans who have collected stamps may not be unfamiliar with the first day cover, but many people should be unclear. "First Day Cover" is an envelope with the full set or single piece of the set of stamps affixed to the upper right corner of the special envelope on the first day of the issuance of the new stamp, stamped with the postal date stamp or special commemorative postmark of the day. The actual delivery by the postal department is called the first-day delivery. The first day cover is more and more popular with many philatelists around the world due to its artistry, historical data, and fun in the collection process. This time I shared the scenery, architecture, characters, stories, animals, etc. ~ it is presented with exquisite printing or even bronzing, which is very suitable for collection! *The design hall has been dominated by European antiques, old pieces and old objects, After years of baptism, some antiques will inevitably have some slight historical traces and black spots, Or a small missing corner, it is inevitable that it is not as clean and flawless as a new product, But this does not affect its retro beauty, Friends who are perfectionist and accustomed to buying new products, please think twice before placing an order, We also look forward to you becoming as fond of the beauty of antiquities as we are^^ Please send us any questions!
