Lot# 9099

The cover bears a “美豐銀行” business label, and on reverse are affixed ten undeliverable slips, with the item ultimately returned to the sender on Oct 8, clearly documenting the full process of repeated unsuccessful delivery attempts. This cover is notable for its detailed and well-preserved postal handling records, illustrating no fewer than ten delivery and return attempts over approximately one month, substantiated by multiple delivery markings. Such an example represents a rare instance of actual postal operations. In the context of the unsettled post-war conditions and urban disruption, it provides important insight into the delivery system, operational procedures, and diligence of postal staff in Chungking around 1949, and holds significant postal history and exhibition value.
