The collection consists of 42 printed maps of the city of Rome, dating circa 1550 to 1883, from the library of collector,
gallerist, philanthropist and patron of the arts, Countess Anna Laetitia Pecci-Blunt.
Anna Laetitia ("Mimì") Pecci-Blunt was born on 15 March 1885. Her father, Count Camillo Pecci was head of the Guardia nobile
pontificia and a nephew to Pope Leo XIII (Vicenzo Gioacchino Pecci), and her mother, Silvia Bueno y Garzon was a Spanish noblewoman
from Cuba. After passing the years of World War I in Switzerland, Anna Laetitia Pecci settled in Paris and soon immersed herself
in artistic and intellectual circles, becoming friends with Georges Braque and Jean Cocteau. She was introduced to the wealthy
and cultured American banker, Cécil Blunt, son of the collector Ferdinand Blumenthal. The marriage between the two was celebrated
in 1919 with the benediction of Pope Benedict XV, who gave Cécil Blunt the title of Count Pecci-Blunt. The couple took up
residence in Paris where they opened their home to writers, poets, artists and musicians including Salvador Dalì, Cocteau,
Paul Valéry, Francis Poulenc and Paul Claudel. The Pecci-Blunts had five children: Dino, Laetitia,
Viviana, Camilla and Graziella.
