1866 Shanghai SG:28, Chan:LS28 Large Dragon 1ca printing #52 with modern numeral "1" used with a virtually complete LOCAL POST OFFICE NINGPO small garter cancellation in red, small margins as normal. A new discovery and extremely rare, probably unique.According to Dr. Wei - Liang Chow "Only about twenty copies of the Shanghai Local Post Large Dragon stamps bearing the Ningpo postmark of this type, all of them except three are the 1ca stamps Printing #48, the three exceptions are the 1ca stamp of Printing #22, the 6ca stamp of Printing #36 and the 3ca stamp of Printing #50". This means that 1ca stamp Printing #52 with this Ningpo cancellation has never previously been recorded.Ref. Treaty Ports of China Sotheby´s Hong Kong November 7, 1996. 1866上海工部大龙一分银第52号印刷模号, 现代数字"1", 盖几乎完整的红色甯波信馆绶带戳, 票为常见的窄边. 此票为近期新发现, 极其罕见, 极有可能为孤品.据周炜良博士介绍：上海工部大龙邮票只有约二十枚盖有甯波信馆绶带戳，除三张外均为一分银第48号印刷模号，其余三张为一分银第22号印刷模号，六分银第36号印刷模号及三分银第50号印刷模号。 这意味着盖有此甯波信馆绶带戳的工部大龙一分银第52号印刷模号以前从未注著录过.参见: <<中国通商口岸>>拍目相关拍品-苏富比香港 1996 年 11 月 7 日.
