Mendoza's provincial treasury notes from this period existed because the Argentine national banking system had not yet fully absorbed the interior provinces into a coherent monetary framework — local commerce needed instruments the federal system wasn't supplying. Guillermo Kraft's Buenos Aires lithography house was the dominant commercial printer of the era, handling everything from railway timetables to official documents, which says something about how these provincial emissions were procured: through commercial contract, not through a dedicated security printer.

The PS prefix in the Pick catalog places this squarely in the provincial and state issues supplement — a category that remains underresearched relative to Argentine national issues.
