1903- Macau Postal Card uprated and registered via Kowloon Customs A blue Macau Postal Card franked with a Portugal King Carlos 10 Reis adhesive, addressed to England. Upon arrival in Hong Kong, the card was additionally franked with a Hong Kong Queen Victoria 10c stamp, tied by a fine strike of the double-ring “CUSTOMS KOWLOON / SEP 24 / 1903” c.d.s. Registered by the Hong Kong G.P.O. on 25 September, showing black registration label “R / HONGKONG CHINA / No. 3315”, and an oval London Registered arrival datestamp in red dated 26 October 1903. On the face are manuscript registration markings in blue crayon “137” and a registration cross in both blue and red pencil. This is a highly unusual and important postal history item: a Macau postal card carried into the Hong Kong system, where it was uprated and registered through Kowloon Customs, then processed by the Hong Kong G.P.O. for transmission to England. Very few examples are recorded showing the rare Kowloon Customs datestamp applied to registered Hong Kong overseas mail, making this a significant cross-jurisdictional usage between Macau and Hong Kong and a desirable exhibition item for both Macau and Hong Kong postal history collections.1903年 – 澳門明信片經九龍海關加貼掛號 藍色澳門明信片，貼葡萄牙卡洛斯國王10雷亞郵票，寄往英國。到達香港後，再加貼一枚香港維多利亞女王像10仙郵票，並蓋「CUSTOMS KOWLOON / SEP 24 / 1903」雙圈日戳清晰銷訖。其後於9月25日由香港總郵政局掛號，貼有黑色掛號號籤「R / HONGKONG CHINA / No. 3315」，另於1903年10月26日蓋有紅色倫敦掛號到達日戳。信面上並見藍色蠟筆“137”號碼及藍紅色十字掛號標記。此為一件極罕見兼具重要意義的郵史實物：澳門明信片經香港轉遞時，由九龍海關銷訖並加貼香港郵票作掛號郵寄，再交香港總郵政局轉寄往英國。已知蓋有九龍海關日戳的掛號香港海外郵件極為稀少，本件展現了澳門與香港之間跨境郵政聯合合作的珍貴範例，對於澳門及香港郵史收藏均屬難得之展品。
