Syndicato Condor

Syndicato Condor Ltda. was a private airline based in Brazil that provided airmail service using their own stamps. The stamps paid for airmail service; Brazilian postage was still required on mail. The original domestic service was soon extended to neighboring countries and (experimentally) beyond to transatlantic mail.
