This note is a legend in the annals of banknote collectors, the legendary Gypsy Lady was long conjectured to be an actual woman, a Spaniard named Gloria Faure that had a reputation as a lover of many including of 1920's Mexico's Finance Minister, Alberto J. Pani, and also President Plutarco Elias Calles. Whilst it is known for fact that she circulated amongst many politicans during that era, it has never been proven that she is in fact the portrait on the 5 Peso note that was issued from 1925 to 1972. American Banknote Company archives suggest the image is actually referred to as "The Ideal Head of an Algerian Girl" and may have been originally intended for another work. Whatever the fact about the note, the design makes for interesting legend and served Banco de Mexico for 47 years. This note is P-59h.
