Advertising poster for the French bank Societe Generale, 1920.
In 1895, Société Générale had 14,000 shareholders. In 1913, they numbered 122,000. The war years were difficult and had serious consequences with the loss of Russian business. However, during the 1920s Société Générale became France's leading bank: its network had grown sharply since the 1890s, with a huge number of branches and seasonal offices allowing in-depth penetration of the provincial market (260 seasonal offices in 1910 and 864 in 1930).
