500 Pesetas

Bradbury Wilkinson's involvement with Spanish currency was extensive in the early twentieth century, and this 1907 note reflects that relationship. The firm's London works produced the intaglio printing, with the finished notes shipped to Madrid for signature and issue — a arrangement common to several Banco de España series of the period.

José Sánchez-Guerra, one of three signatories, would later serve as Prime Minister of Spain (1922–23), making his appearance here as a bank official a minor biographical curiosity for political historians. The three-signature authentication requirement was a deliberate internal control mechanism adopted by the Banco de España during this period, not standard practice across European central banks at the time.
