20世纪80年代初,在京、沪、杭地区,已有不少收藏界的人士,利用邮票(最早人们称之为“邮花”)和火柴商标(人们以雅号称之“火花”),创作出许多受人喜爱的连袂封,起初名称不一,有曰“二花封”有曰“二宝封”。笔者也参与定名的讨论,中药有味药名叫“双花”俗名“金银花”,大家同意“双花封”这个名称。 In the early 1980s, in the Beijing, Shanghai and Hangzhou regions, there were quite a few collectors who used stamps (the earliest known as “postal flowers”) and matchmarks (which people call “Sparks” with nicknames) Out of many loved one by one seal, initially different names, there are said “two flower seal” there is “two treasure seal.” I also participate in the discussion of naming, Chinese medicine has a taste of medicine called “double flower” common name “honeysuckle”, we agree with the “double flower closure” the name.
