Airmail aerogramme is a postal article between postcards and letters, also known as aerogramme. When a stamp is sold, it is just a piece of paper. One side of the paper is like the cover of an envelope. You can write the name, address and postal code of the recipient. The other side plays the role of writing paper, and the sender can write the text of the letter. After writing, fold it according to the folding line on the paper to form a letter shape. Postcards are postal products printed and distributed by postal departments, which are a trinity of postage certificates, envelopes and stationery. They are divided into printed postage maps and non-postage maps. When mailing, it is not allowed to put other stationery in the aerogramme.

Postage aerogrammes, like stamps and envelopes, have a history of over 100 years. It originated in the early postal period in Europe. People used to write letters on a page and then fold them up and send them. 18 19, the kingdom of Sardinia in southern Italy issued a watermark stationery printed with a postman pattern riding a horse and blowing a horn. After being postmarked, the seller sends the letter. This is the prototype of the postal envelope. 1840, Britain issued a "black penny" stamp and postage envelope, and also issued an airmail aerogramme designed by Maldi. The front of Jane is painted with patterns such as people reading letters, writing letters, barter, postal delivery, and postal advertisements are printed on both sides. This is the earliest ordinary posting box in the world, and it is also the earliest artistic advertising posting box. Later, other European countries began to issue aerogrammes. Japan was the first country in Asia to issue aerogrammes, and in 1873, a set of six ordinary aerogrammes was first issued.

19 18 years, China first issued vertical stamps with specifications of 84 mm× 145 mm; The postage map is oval, and the main map is wheat ears, with a face value of 3 points; The words "postal service of the Republic of China" are printed on the top of the wheat ear map, and the words "postal stationery" are printed on the bottom. 1950, People's Republic of China (PRC) (PRC) first issued the "Pudong 1" stamp with a face value of 5,000 yuan. Thus, the Northeast Stamp Series, numbered "PJD" (Universal, Simple and Oriental) was formed. This series has only been published for two years. Since 1952, China has issued another ordinary stamp, numbered "PJ", which only existed for more than 9 months. These two series of postage stamps are "passers-by" in the early days of the founding of the People's Republic of China, and it is difficult to see them in the postal market at present. Although the full set of national quotations exceeds 10,000 yuan, they are still valuable and out of stock.
