The fact that the dam was built during the Great Depression and that it cost a lot of money and also the lives of many workers, kept it in the spotlight. It still serves the purpose it was built for almost a century ago and its intrinsic beauty is showcased by the Hoover Dam posters.
There are plenty of reasons for why prospective customers would prefer Hoover Dam photos in black-and-white, is that of the colored versions. Some were taken in the years following the grand opening, when the dam was even more impressive because it was one of the largest ever built. Even though these kinds of structures are not traditionally regarded as a great source of inspiration for artists and rarely serve decorative purposes, the Hoover Dam pictures are the exception to the rule. They are impressive on many levels and make it impossible for those who noticed them to look away.
