Spent some time reorganizing a binder of covers and booklets and came across this cover from Australia that was interesting enough that I kept it. Funny how often that happens with stuff we do not normally collect. They do show up for sale.
I had researched it before and was able to find the link below again that explains the history of of the Provisional International Civil Aviation Organization (P.I.A.C.O.) The little note inside was kind of cute too. applications.icao.int/postalhistory/from_picao_to_icao_organizational_similarities.htm
