2011年12月11日,中国加入世贸组织10周年之际,中国邮政发行纪念邮资封一枚。笔者收到一枚邮友从北京寄来的首日封,一眼就看到上面盖的“北京/2011.12.11.20/中南海4”邮戳有点色彩差异,仔细一看,原来是剪贴的邮戳。从背面看,这个戳片纸下盖的竟然是“北京/2011.12.10.20/中南海4”戳,这样一来,就可以猜测,当时盖销处理信件时,字钉时间没有及时更换,事后才发现日期错了,就在白纸上盖上正确的日期,然后再剪裁下来,贴在错误的邮戳上。 On December 11, 2011, on the occasion of the 10th anniversary of China’s accession to the WTO, China Post issued a memorandum of commemorative postage. I received a postal mail from Beijing, the first day cover, one saw the above cover “Beijing /2011.12.11.20/ Zhongnanhai 4 ” postmark a little color difference, a closer look, the original is a scrapbooking postmark. From the back of the look, this stamp sheet of paper under the cover turned out to be “Beijing /2011.12.10.20/ Zhongnanhai 4 ” stamp, this way, you can guess, when the letter is canceled cover letter, the word nail time is not timely replacement, afterwards Only to find the date wrong, the white paper on the correct date, and then cut and posted on the wrong postmark.
