Together with three of his sons, Aldo Gucci (1905?1990), Vasco Gucci (1907?1975), and Rodolfo Gucci (1912?1983), Gucci expanded the company to include stores in Milan and Rome as well as additional shops in Florence. Gucci?s stores featured such finely crafted leather accessories as handbags, shoes, and his iconic ornamented loafer as well as silks and knitwear in a signature pattern. The Gucci loafer is the only shoe in the collection of the Museum of Modern Art in New York. The company made handbags of cotton canvas rather than leather during World War II as a result of material shortages. The canvas, however, was distinguished by a signature double-G symbol combined with prominent red and green bands. After the war, the Gucci crest, which showed a shield and armored knight surrounded by a ribbon inscribed with the family name, became synonymous with the city of Florence.
