Background: First International Air Post Congress at The Hague, Netherlands, initiated by USSR, held from 1 to 10 September 1927.

This Conference resulted in an agreement that established the airline companies as officially recognized carriers of mail at the maximum remuneration of 6 postal gold francs per metric ton-kilogram. It also initiated some significant rules and regulations concerning the acceptance and rapid delivery of airmail by the signatory powers, the expeditious handling of airmail by countries without air services, and the basis of accounting procedures for international airmail. Another provision agreed upon was that the par avion labels should have a blue colour and, when the mail did not actually travel by air, such labels or annotations should be crossed out. The The Hague Conference of 1927 laid down the first airmail provisions, an event of historic importance in view of the fantastic development of that means of transportation in the international post. The UPU London Congress adopted in 1929 with minor changes the Air Mail Regulations that were established by this Conference.

Numerous varieties are found for this set, due to the many white, blue or red ink spots, broken frames, etc. created on the stamps at the time of printing. Only the major ones clearly noted in the postage stamp catalogues are described here-above.

It can be noted that the centering of the stamps is fair, i.e. the stamp design is not located perfectly in the center of the paper with all four margins being precisely the same.

During the conference, a special postmark was used to commemorate this occasion in the Netherlands. Text on the postmark reads as follows: CONFÉRENCE / POSTALE LA HAYE / 9-IX-1927-19-H, along the three equilateral sides of the triangle. In the middle, are the world globe and the letters U P U.
