Brazil 893

Brazil #893 was issued on July 16, 1959 to commemorate the 150th anniversary of the Carmelite Order in Brazil.  The design features the facade of a pipe organ.

Thankfully Handel Cecilio has written a dissertation on the organ.  A good picture is found on pages 56 and 57 of his work which is available online:  http://www.archive.org/details/TheEighteenth-centuryPipeOrganAtTheCarmelChurchInDiamantinaIts
