STAMP ISSUES RELATED TO ICAO (1984-1985)

 

Bulgaria : 40th Anniversary of ICAO

 

Issue date: 25/12/1984

 

 

TupolevTu-154B-2 of Balkan Air and ICAO emblem.

 

Lower-left block of 4 stamps.

Full sheet of 20 stamps.

The text at the bottom margin of this sheet is interesting and shows two errors. The beginning of the translated text reads as follows: Commemorative stamp 40 years of the International civil airline organization ИКО.

The text after that refers to the price, the printing process and the related authorization.

1.      Although the stamp designates correctly (in Bulgarian) the International Civil Aviation Organization, the margin uses the word airline (in singular form) instead of aviation.

2.     The second error comes from the Cyrillic acronym of the Organization (which should be ИКАО). The letter A is missing in the acronym.

The text after that refers to the price, the printing process and the related authorization.
