Corrientes was the only Argentine province to issue its own postage stamps before the national government did — and its banknotes of the same period reflect the same improvised, self-reliant character. The provincial government operated with considerable autonomy through the 1840s and 1850s, and these paper emissions were essentially instruments of local fiscal necessity rather than products of any central monetary authority.

The official stamp as the primary security feature points to a note authenticated at the point of issue rather than during printing — a common workaround when access to specialist security printers was limited or nonexistent.
