Ureta was a farmer on a ranch in the 1970s and owned land in the Argentine Pampas, east of Buenos Aires.
One day, while flying over the region, his wife Graciela noticed a field in a strange shape – a bucket of milk.
Inspired by that idea, she suggested planting a field on their land that would outline some shape when viewed from above. Ureta agreed, but the job and raising a young family meant that the couple never had a chance to carry out their plan.
Unfortunately, Graciela died suddenly in 1977 at the age of 25 from a brain aneurysm. Sad that he never managed to fulfill his wife’s wish, he decided to plant a field in her honor.
As she was a great lover of music, he decided to design a complex pattern that would look like a guitar, her favorite instrument.
