These stamps were printed in sheets of four for use on the return flight of the Dornier DO-X from New York to Germany. Newfoundland mail was accepted for despatch by the DO-X, to be prepaid by Newfoundland stamps. According to the Sanabria catalogue, a total of 8,000 stamps with the DO-X surcharge were printed. Of these, 50 received inverted surcharges. Current estimates of the number known vary between 20 and 40. The Killien example is among the very finest known.
