This is one of three stamps issued for use on mail carried by the German
dirigible, built and commanded by Dr. Hugo Eckener.
This special flight was from Germany to Spain, Brazil, and the United States,
and back to Spain and Germany, during May and June, 1930.
A former newspaper reporter and an early critic of Count Ferdinand von
Zeppelin's experiments with dirigibles, Dr. Eckener became a pilot, and in 1921
manager of the Zeppelin enterprises.
He built and delivered to the United States the dirigible Los Angeles as part
of reparations for World War I.
Although more than a million copies of each of the three stamp values were
printed, their sales were disappointing. When the stamps were withdrawn from
circulation on June 30, 1930, more than 90 percent of them were destroyed.
