1894年12月24日宜昌寄上海无票封, 由欧尔森(Joseph Olsen)寄给邮票设计者费拉尔(R.A.de Villard); 在信封面左上端以红墨水写上英文宜昌, 在封背盖有黑色方框型重庆信局宜昌分局中英文日戳, 12月29日蓝色汉口工部日戳, 模糊的1895年1月1日上海工部日戳及蓝色上海海关到达日戳, 另有邮差铅笔记录. 罕见的早期宜昌无票实寄封, 而且不惯常地经上海海关邮政递送, 更是中国早期商埠邮政史的难得素材.1966年11月周炜良.Ichang Opening of Ichang Post Office 1894 (24 Dec.) stampless de Villard envelope to Shanghai with the address side marked "Ichang" in red ink and, on the reverse, a good strike of Ichang oblong datestamp in black, Hankow Local Post c.d.s.
