The exhibition explored the friendship of the painter from the town of Valdepeñas with members of his generation, the Generation of 27, especially with Federico García Lorca, whom he met in 1924 in Pinto's exhibition at the Museum of Art Modern, Madrid, and with Luis Cernuda, a friendship that began in the late 1920s, in Madrid, and continued in 1938, in England. The show also dealt with Prieto's relationship with other poets and painters, such as Concha Méndez, Manuel Altolaguirre, Alfonso Reyes, Vicente Aleixandre, Juan Chabás, Enrique Diez-Canedo, Max Jacob, Filippo de Pisis and Filippo Marinetti. The core of the exhibition consisted of testimonies, such as letters, portraits, photographs and other documents from the Fundación Gregorio Prieto and the Residencia de Estudiantes. There was also a selection of his paintings, and his drawings for periodicals such as Alfar, La Gaceta Literaria, Litoral and Verso y Prosa, and for publishers such as Gallimard and GLM.
