拍品描述： 1894年8月12日镇江寄本埠红条对, 贴第一版一分票, 销完整及清晰镇江双圈日戳, 此外并无其他邮政记号, 由于镇江书信馆发行的邮票于8月6日才开始, 相信亦是使用镇江双圈英文日戳最早期的实寄封.Chinkiang Covers Internal Mail 1894 (12 Aug.) red band envelope used locally bearing first issue 1c. tied by a neat strike of smaller "chinkiang/postal service" c.d.s., no other postal markings. There is a punch hole in the lower corner. Very early use of these stamps which were issued on 6th August, possibly the earliest date for an extant cover. Photo
