Design of a reverse for a 1,000 pesetas banknote without date, on yellow cardboard and green ink. This sketch is constructed as a collage from a basic ink design to which printed guilloché borders and an empty circle have been added to demarcate the watermark window. At the bottom of the card is mentioned "Series: Cervantes", in reference to the intention of the Bank of Spain to dedicate a complete series of banknotes (the 1951 series) to the famous writer, his work and his characters. From this project we have the 1 peseta note from 1951 dedicated to Don Quixote and we also know a sketch of 25 pesetas dated July 7, 1952 with which this reverse shares the rectilinear style of the borders and placards with the name of the Bank from Spain. Possibly, this reverse of 1,000 pesetas was that of the banknote dedicated to Miguel de Cervantes himself. For unknown reasons, the 1951 series evolved in other directions that have nothing to do with the brilliant writer. However, what is certain is that it is a design that, with minimal modifications (the micro-printed texts in the corners under the denominations were replaced by fruit ornaments), was used, as indicated by Don Ramón Cobo Huici, on the reverse of the 1,000 pesetas banknote of 1951. This banknote began to be manufactured in 1953, which would allow the date of this project to be set at the end of the 1940s or perhaps in 1951 or 1952 as part of the development of the banknote dedicated to Sorolla, which makes it a very interesting specimen to complement this period.
