What do the three elements of stamps mean?

The three elements of stamps generally refer to: country name, face value and design.

Country name: the name of the issuing country or region printed on the front of the stamp. Generally, it is expressed by words and abbreviations. For example, "China People's Post" has been used on new China stamps, and "China Post China" has been used since 10/992 when the "Renshennian" stamp was issued on October 25th. However, there are also some countries that do not indicate the country name, but use special symbols to express it. For example, Britain has always maintained the tradition that the first "black penny stamp" of 1840 was not marked with the country name, but was replaced with the head of the Queen of England.

Face value: the postage amount and monetary unit printed on the surface of a stamp. Most countries in the world use Arabic numerals to express the postage amount. For example, the face value of new China stamps is 20 cents, 50 cents and so on. There are also some countries or regions that have issued stamps without face value. For example, from 1978 to 1985, the United States issued stamps with the words "a", "b", "c" and "d" successively. This situation is generally a transitional measure during the adjustment of postage.

Pattern: the picture of a stamp, which is the most vivid factor among all elements of a stamp, can be divided into two parts: the main picture and the frame. Because stamps are called "national business cards", countries all over the world take the most representative contents of their own countries in politics, metallurgy, economy, national defense, science and technology, culture and art, history and geography, natural scenery, precious animals and plants and so on as stamp patterns, which makes you fondle admiringly.
