自古民间就有“谷米让人吃饱,蔬菜让人吃好”一说,每当人们聊起“营养”、“健康”的话题时,总会提及蔬菜的作用。由于它与人类的生活息息相关,被选作邮票题材也在情理之中。1958年9月20日,距世界首次发行邮票118年零4个多月的时间,第一套以蔬菜命题的邮票才迟迟面世,由保加利亚发行,邮票单色印刷,一套六枚,图例“圆葱”为其中之一。 Since ancient times there is “people full of grains of rice, vegetables make people eat well,” said that whenever people talk about “nutrition” and “health” of the topic, always mentioned the role of vegetables. Because of its relevance to human life, it is reasonable to be chosen as a stamp subject. September 20, 1958, the world’s first stamp of 118 years and more than 4 months time, the first set of vegetable stamps issued only after the delay, issued by Bulgaria, monochrome stamps, a set of six, the legend “Onion” is one of them.
