The above shows a commercial cover sent to Dr. A. Roper as Secretary General of PICAO, with a postmark dated 12 May 1947 (a few weeks after ICAO came into being); news regarding the establishment of the permanent ICAO had not flown fast enough to reach the ministries of all governments.

At the time of the marriage of Albert Roper’s parents, the scribe of the Town Hall of Dinan, France, had spelled ROPER (instead of ROPERT) the name of his father. As this marriage booklet was thereafter used for the establishment of the birth certificate of Albert, his name was written without final T on all his official papers; whereas Albert Roper always signed with T, so that at the college and the regiment, everyone knew him under the name of ROPERT. It was only at the end of the war 1914-18 that he decided to give up any procedure of correction of all his official papers and birth certificate. Since then, he signed ROPER without T, surprising everyone. However, this envelope, sent from Argentina in 1947, spelled the name with T. This is extremely interesting when one knows the origin of the error on the name.

In Fresnes, the “impasse des Sentiers”, where Albert Roper and his parents lived at #10, has been renovated and extended; it became an important traffic lane and was renamed “rue Albert Roper” by the municipal council on 21 December 1988. (Source Wikiwand). |

Cover sent from Kosovo’s CAA to Mr. R. Benjamin, Secretary General. Postmarked 7 December 2009. Note that the above stampless cover was postmarked in Kosovo on 7 December 2009, i.e., on the exact day of ICAO’s 65th anniversary. It was again postmarked at the entrance into Canada on 21 December 2009 by Canada Post (H4T 1A0 postal code, at the main sorting plant of MacArthur Street in the borough of Saint-Laurent, Montreal), which had developed a special postal code H0H 0H0, as per the following story. In 1974, staff at Canada Post’s Montreal office was noticing a considerable number of letters addressed to Saint Nicholas coming into the postal system, and those letters were being treated as undeliverable. Since those employees did not want the writers, mostly young children, to be disappointed at the lack of response, they started answering the letters themselves. The amount of mail sent to Santa Claus increased every Christmas, up to the point that Canada Post decided to start an official Santa Claus letter-response program in 1983. Approximately one million letters come into Santa Claus each Christmas, including from outside of Canada, and all of them are answered, in the same languages in which they are written. Canada Post introduced a special address for mail to Santa Claus, complete with its own postal code: SANTA CLAUS, NORTH POLE, H0H 0H0, CANADA. In French, Santa's mail is addressed to: PÈRE NOËL, PÔLE NORD, H0H 0H0, CANADA. H0H 0H0 was chosen for this special seasonal use as it reads as "Ho ho ho"....
