Before Ian McQueen published his study, references to these markings were scattered across various regional articles and auction catalogs. McQueen gathered these disparate threads into a cohesive, scientific study. He meticulously categorized the markings, analyzed their postal rates, and mapped the specific air routes that triggered their use.

: Transit and arrival stamps on the reverse of the envelope must be tracked chronologically to confirm the exact date the letter transitioned from air to surface transit. Legacy of the Study Jusqu'a Airmail Markings. (A Study) by MCQUEEN Ian

If you want to explore specific aspects of this philatelic topic further, please tell me:

When a postal clerk stamped a cover with a jusqu'à marking, they typically wrote or stamped a specific city name immediately following the word "Jusqu'à" (e.g., "Jusqu'à Karachi" or "Jusqu'à Singapore"). Handwritten adjustments made by postal clerks in smaller

They helped postal clerks determine the quickest and most efficient routing.

The very existence of these markings is a fascinating story born from the infancy of aviation. In the early 20th century, air travel was expensive, and routes were limited. A sender in one country might pay for an airmail letter to be flown only part of its journey, with the remainder to be carried by slower, cheaper surface transport—a sort of "partial airmail" service.

During WWII, shifting front lines and grounded civilian fleets led to a surge in "Jusqu’à" markings as air routes were truncated or diverted. 4. Philatelic Significance

(meaning "until" or "as far as") represents a critical chapter in 20th-century aerophilately. Ian McQueen’s seminal study remains the definitive guide to these markings, which were applied to mail where airmail service was only paid for or available for a specific portion of the journey. This paper outlines the functional necessity, typographic variety, and historical significance of these markings as documented by McQueen. 1. The Functional Necessity of "Jusqu’à" I need to gather information about Ian McQueen,

McQueen provides detailed listings for over 150 distinct markings, noting periods of use, rarity, and known covers.

McQueen's study reveals that jusqu'a airmail markings were primarily used on mail sent during World War I, particularly between 1914 and 1918. The distribution of these markings was largely limited to areas where airpower played a significant role in military operations, such as:

For decades, these markings remained a highly specialized, poorly understood niche of aerophilately. That changed with the publication of the seminal research work, . Published by the Celestial Tiger Press in 1993, McQueen’s monograph transformed a scattered assembly of anomalous postmarks into an organized, scientifically categorized field of philatelic study. For serious collectors of airmail postal history, McQueen’s book remains the definitive, foundational bible on the subject. The Historical and Postal Context of "Jusqu'à"

True postal history pieces show a direct correlation between the stamps affixed and the partial-air rate of the era. Cross-reference the postage with historical tariff tables to ensure it is not a philatelic creation.
