1000 Escudos

The Banco Nacional Ultramarino operated as a note-issuing authority across Portuguese overseas territories rather than functioning as a conventional central bank for metropolitan Portugal. This 1959 issue would have circulated in one of those territories — most likely Portuguese Guinea, Angola, Mozambique, or another possessions under BNU mandate — though the specific territory is not distinguished by the Pick number alone without additional overprint or serial prefix data.

Thomas De La Rue's involvement was typical for Portuguese colonial currency of this period, the London firm having held printing contracts across the BNU's territorial issues for decades. At 1000 escudos, this was a high-denomination note relative to everyday wages in any of the territories it served.
