This is a very superior set that you can be proud of. President Herbert Hoovers Postmaster GeneralWalter F. Brownwho served from March 5, 1929 to March 3, 1933 oversaw one of the greatest collector nightmares in the history of the United States Postal Service.
The set of three stamps were used briefly as intended (on first day and Zeppelin first flight covers) and then withdrawn from public sale when that collector backlashat the beginning of the Great Depressionbecame too much for the Post Office Department to bear. The Post Office destroyed huge amounts of unsold stamps because of poor sales.
