1 Peseta Sena

Sena is a small municipality in Huesca, Aragon — and like hundreds of Spanish towns during the Civil War, it issued its own emergency fractional paper when coins vanished from circulation almost overnight after July 1936. The Consejo de Sena's 1 Peseta note is among the smallest-format pieces to emerge from that period, a square format that itself suggests local improvisation rather than any coordinated printing arrangement.

The Gari Monetary catalog reference is incomplete, which places this among the less-documented Aragonese locals — attribution is secure, rarity is not.
