Provincial currency from San Luis sits in an awkward historiographical gap — Argentina's interior provinces issued their own notes during periods when the federal banking system either collapsed or simply failed to reach them, and San Luis was among the smaller, more financially precarious of these issuers. Ciccone Calcográfica, the Buenos Aires intaglio printer responsible for a significant share of Argentine provincial and national security printing through the late twentieth century, handled the physical production here.

The PS# reference being unassigned suggests this note hasn't been formally catalogued in the Pick Specialized series — worth flagging for any collector building a complete provincial Argentine run.
