Manuel de Falla y Matheu (] , 23 November 187614 November 1946) was a Spanish composer. Along with Isaac Albéniz and Enrique Granados, he was one of Spain's most important musicians of the first half of the 20th century. His image was on Spain's 1970 100-pesetas banknote.
Neither Isaac Albéniz nor Enrique Granados appear on Spain's banknotes.
The context only mentions that Falla was on a banknote and does not say whether the other leading composers of his time were on banknotes, so it is impossible to say whether they were. The model is probably fooled by the fact that only Falla is mentioned as being on a banknote.
