This book is an account of how the United States of America and the United Kingdom co-operated during World War II to run a censorship and intelligence-gathering operation on mail travelling between the Axis countries in Europe and countries in Latin America with pro-Axis sympathies. Pan American Airways took the place of the Italian-owned LATI (Linee Aeree Transcontinentali Italiane) transatlantic airmail delivery service, which had started in 1939 but was terminated by the USA following that country’s entry into the war in December 1941. The allied censorship operation was based in San Juan, Puerto Rico, and had not been the subject of study hitherto. This lavishly illustrated book tells the story of the airmail routes and the censorship process that were developed. The authors used a combination of archival materials and relevant covers to tell its story.
In 2021, the Royal Philatelic Society London published the book as a paperback of 312 pages. It then cost £44 (£39 for members). It was fully sold out before long. Now, the society has released a digital edition of this book. Anyone can purchase it from the RPSL website for £20 (it is free for members!)
