In the 1920s, the United States experienced spectacular economic growth stemming from new technology developments and government policies that aided big business. Investments in stocks and corporations increased dramatically, providing new capital for corporate expansion both in America and globally. Beginning in September 1929, the stock market began to decline and falling prices prompted investors to sell. By October 29, "Black Tuesday," panic-stricken investors had sold so much stock that the resulting low stock values caused the market to collapse. This catastrophic event precipitated a worldwide economic slump that affected all Western industrialized countries. The crash, combined with other economic factors, led to the Great Depression and the most difficult decade of the 20th century. Image Size: 9.25 x 13.75 in. Overall Size: 14.25 x 20 in. Unframed.
