The correct answer is Between World War I and the Great Depression.
The time period described in the aforementioned answer choice refers to the era of the 1920's. Thanks to a successful economy and low unemployment rate, this era saw a huge increase in advertisement. American citizens had more disposable income at this time, meaning they could buy luxury goods. Along with this, the ability to buy goods, like cars, through installment plans helped tremendously. Advertisements like the one showed above were common in America during the 1920's as car dealers like Ford and Chevrolet competed to develop affordable cars for the average American.
