Hoover Boulder Dam foldout postcard 

Bold, large letters and detailed illustrations help to capture and share the publisher's perception of the Hoover Dam  in the 1950s. The detailed imagery on the outside, and within the postcard, is accredited to halftone printing. The postcard opens like a folder, and holds 9 postcards that feature imagery on the fronts and backs.  Different locations relating to the Hoover Dam are provided alongside their corresponding print, such as the Hoover Boulder Dam Powerhouse and the Transcontinental Highway across the Hoover (Boulder) Dam. All of the postcards are printed on one long strip of paper, folded to resemble an accordion and fit within the folder portion of the postcard. The inside of the folder describes various facts about the Hoover (Boulder) Dam including its cost to build, its height, its primary purposes, and nearby notable locations. The previous owner of the postcard documented their visit on March 19, 1953. Throughout the postcards, small notes can be seen within the borders of the print and the paper, documenting the locations they visited on the property. 

The folder was published by Curt Teich & Co. sometime in the 1940s to 50s. The postcard refers to the Hoover Dam as the Boulder Dam in parenthesis. The dam was orginally named the “Boulder Dam” upon its creation as it was build within the Boulder Canyon, located in Nevada. However, the dam was renamed the “Hoover Dam” in 1947 by congress, after President Herbert Hoover. The significance of the postcard can be deciphered through its detailed imagery and remarkable  information about the Hoover Dam, pushing America to travel and experience the “world's most impressive engineering sight.” Postcards such as this one were created as a way to advertise the location featured through the personal connection of the sender and the receiver, increasing the opportunity to promote business effectively. Not only did the postcard remind the receiver that the sender was thinking of them, but it was also personal recommendation to visit the location advertised on the card.
