BARCELONA, Spain - Pablo Picasso, the world famous Spanish painter, is being reunited with his lifelong friend, countryman and fellow artist, Joan Miró, in a unique dual exhibition in Barcelona.

Marking the 50th anniversary of the death of Picasso, Miró-Picasso is the name of the exhibition jointly organized and hosted simultaneously by the artists' respective museums in the city — the Picasso Museum and the Joan Miró Foundation.

Running until Feb 25 next year, Miró-Picasso explores the close personal and artistic relationship the two artists had with each other and with the city where the two men established their artistic legacies

Running until Feb 25 next year, Miró-Picasso explores the close personal and artistic relationship the two artists had with each other and with the city where the two men established their artistic legacies.

"This exhibition had to be in Barcelona because both artists entrusted their legacies to the city of Barcelona and not only did Picasso and Miró donate a large part of their works to the city but they were behind the creation of the two museums that bear their names," said Sònia Villegas, one of the curators of the exhibition at the Joan Miró Foundation.

"Here there are a lot of artworks from the Barcelona Picasso Museum and we have displayed a lot of works from the Miró Foundation there in order to make this reunion, this physical conjunction of the two artists in both museums," she added.

The exhibition brings together 338 artworks from public and private collections from all over the world with the aim of exhibiting side by side two artists who together transformed the art of the 20th century.

"It's unique because it is the first Miró-Picasso exhibition of this size with so many artworks but it's also unique because it's the first time the Miró Foundation of Barcelona and the Picasso Museum in Barcelona have put on a joint exhibition," Elena Llorens, curator of the Miró-Picasso exhibition at the Picasso Museum, told Xinhua.

About 76 of the paintings on display have never before been exhibited in Barcelona, and some of them never in Spain, and the exhibition contains such rarely seen masterpieces as The Farm and Woman, Bird, Star by Miró or The Three Dancers and Las Meninas by Picasso.

Among the museums which have lent artworks to the exhibition are the National Gallery of Art in Washington, the Picasso Museum and the Center Pompidou in Paris, the Tate gallery in London and New York's Museum of Modern Art.

"I heartily recommend anyone who comes to Barcelona visit this exhibition because it's a unique opportunity to see the greatest works of these two artists and it's an exhibition that is unlikely to be repeated," Llorens said.
