Jusqu-a Airmail Markings- A Study Ian Mcqueen

While "Jusqu'à" markings are most famous in standard maritime mail (indicating the port where a sea journey ended and land transport began), McQueen’s book explores how these concepts apply to . Specifically, it investigates markings that denote:

The original was released as a comb-bound reference guide packed with comprehensive illustrations. It broke down the structural typographies, ink variations, and historical Universal Postal Union (UPU) regulations governing these markings. 2. The Massive Supplement (1995)

For decades, these markings puzzled collectors due to their diverse handstamps, manuscript notations, and inconsistent applications. The definitive clarity this subject required arrived with the publication of Jusqu'a Airmail Markings: A Study by Ian McQueen. Published in 1993, McQueen’s pioneering monograph transformed a niche aerodynamic curiosity into a structured, highly sought-after field of philatelic study. The Historical and Operational Context

His work helped collectors distinguish between genuine postal markings and later additions. Why "Jusqu’à" Markings Were Used Jusqu-a Airmail Markings- A Study Ian McQueen

Airmail required complex accounting between nations. When Country A sent mail through Country B's national airline to get to Country C, Country A had to compensate Country B for that aerial transit based on weight and distance.

Cairo and Basra were frequent "Jusqu’à" points for mail heading toward Australia or East Asia. Trans-Atlantic Transitions: While "Jusqu'à" markings are most famous in standard

When an international letter was sent via air mail during the 20th century, the sender typically affixed an airmail stamp or a blue “Par Avion” airmail etiquette . This indicated a request for transit via aircraft for the entirety of the route. However, global aviation infrastructure was heavily segmented, and full airmail transmission to the final destination was not always possible or paid for.

Errors were common: covers with Jusqu’à Marseille that were inadvertently flown beyond Marseille are prized as “overflown” rarities.

The study breaks down usage periods, demonstrating how the markings peaked in the 1930s and gradually vanished in the post-WWII era as all-air transport became universally affordable.

indicating it traveled by air to India and by sea the rest of the way. UPU Compliance:

The study also covers the simple that were often stamped across airmail etiquettes to indicate that the letter would not be carried further by air because of the rate paid. For example, on a 1932 cover from Bridge River, British Columbia, to London, the six‑cent rate paid only for air transport within Canada. When the cover arrived in England, purple bars were struck through the airmail indicators, and the letter then crossed the Atlantic by ship. McQueen’s book documents this and countless similar examples, drawn from many countries.
