From Wassily Kandinsky to Jackson Pollock, the extraordinary impact collectors Peggy and Solomon Guggenheim had on 20th-century art is celebrated by an exhibition that opened in Florence on Saturday.

The exhibition, The Art of the Guggenheim Collections, which runs in the Tuscan city's Palazzo Strozzi through July 24, explores how bohemian socialite Peggy, her uncle Solomon and the celebrated New York museum he established influenced European and American art from the 1920s to the '60s.

Curated by Luca Massimo Barbero, it features paintings, sculptures, photographs and engravings borrowed from the Guggenheim museums in New York and Venice and a small number of other museums and private collections.
