On this stamp issued by Haiti in 1924 and then reissued with an
over-print in 1933 (C4a) to commemorate the flight by J. Errol Boyd
from New York City to Haiti, and finally as a stamp-on-stamp (C176) to
celebrate Aviation Week in 1960.
On the stamp the island designated Haiti is actually
Hispaniola which is occupied by both Hatiti and
Dominican Republic, so it should be designated Hispaniola.
