Lower-left block of 4 stamps.

Full sheet of 20 stamps.

The beginning of the translated text at the bottom margin of this sheet reads as follows: Commemorative stamp 40 years of the International civil airline organization ИКО; it contains two errors:

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.
