Bartolomeo de Oliva (Olives) (fl. 1538-1588) was a member of a
family of chart makers in Mallorca, and later in Messina and
Marseilles. He drew this manuscript map on parchment n Mallorca in
1562. The map is preserved in the Vatican Library. The stamp was
issued in 1935 to call attention to a proposed expedition celebrating
the 4th centenary of Francisco Pizarro's Amazon
expedition. The proposed expedition by Iglesias never took place
because of a civil war in Spain.
