1 Peseta Brull

El Brull is a tiny municipality in Osona comarca, and in 1936 it had a population of only a few hundred people. Like hundreds of other Catalan and Spanish municipalities during the early months of the Civil War, the Ajuntament issued emergency fractional currency because silver and copper coins had been hoarded out of circulation almost immediately after the July uprising. These locally printed notes — collectively catalogued under the generic term "bitllets locals" — were never legal tender beyond the issuing municipality's own commerce.

The nearly square format is a consequence of hand-cutting rather than any design intent. Turró's cataloguing of over a thousand such emissions remains the primary reference for the series.
