我集邮已逾花甲之年了,但一无成就,老的一些邮票都逃脱不了那场浩劫,在横扫一切中全部被查抄而失去了。直到改革开放,集邮事业开始复苏,我的集邮情思才又复燃起来。本文所介绍的“京都三封”便是从我劫余的藏品中拣出来的。这是三枚不贴邮票的实寄信封,分别发生在北京20世纪的不同时期,而收信单位却都是在北京市(含北平市),因而这三枚实寄信封便成为北京邮政发展史的见证。 I philately has been more than a year, but no success, some of the old stamp escaped that catastrophe, all in the swept everything was lost and checked. Until the reform and opening up, the philatelic business started to recover, and my philately thinking was only rekindled. The “three seals in Kyoto” described in this article have been picked out from my collection. Here are three unsent postal envelopes, which occurred at different times in Beijing during the 20th century. However, all of the receiving units were in Beijing (including Peking), so these three envelopes actually became the postal development of Beijing Witness history.
