Both the Portuguese caption and the postmark on this card leave us a little uncertain but we think (after a search) this unused card was issued in 1985.  It involves Parque Nacional Marinho Dos Abrolhos and at least two species of sea birds, Sula dactylatra and Sula leucogaster.  There’s more in the caption but this will do for now.  The unused card issued by Correios e Telegrafos carries serial number 039008.  Aging somewhat.  Grade: 1
