The Argentine authorities were working from existing plate designs, a common cost-saving practice that meant mid-century banknotes sometimes carried artwork conceived in a very different political moment. The Banco Central had been restructured under Perón in 1946, bringing the institution under direct state control after years of a more orthodox central banking model.

The series ran across a four-year window during which inflation was already beginning to erode the peso's purchasing power — the 1 Peso denomination was losing practical relevance even as it was being printed.
