“华邮第一古封”是一个“福利封”。这是集邮家们都知道的。为什么这些实寄封通称“福利封”呢?因为收信者是上海福利公司。120多年前这家公司是干什么的,现在说法不一:有的说是“面包房”,有的说是经营进口轻工业制品和服装的;也许兼而有之。这批信封都是英文封,可是在封的背面有些还用铅笔写上“福利”二字:看来是上海投递局为便于邮差投送,才用中文写上的。 “Huayu first ancient seal” is a “welfare seal.” This is what the collectors know. Why do these real letters known as the “welfare seal” it? Because the recipient is Shanghai Welfare Corporation. What the company did for more than 120 years ago is different now: some say “bakery houses” and others say that they operate in the import of light industrial products and clothing; and perhaps both. All these envelopes were sealed in English, but some were still written on the back of the envelope with the word “welfare”: it appears that the Shanghai Delivery Office wrote in Chinese only for the convenience of postal delivery.
