It doesn't look like it now, though the bones are all still there if you look close enough, but when I was a kid growing up in Las Vegas, McCarran Airport was a mid-century modern oasis.
The new terminal was designed by Los Angeles architect, Welton Beckett and it fit right in with the space age theme that was prevalant back then. From the Landmark tower to the Convention Center, the new terminal would be right at home.
The Nevada State Museum, Las Vegas has a wonderful collection of photographs and negatives from one of the busiest and best photographers of that era, Jay Florian Mitchell. Mitchell came to Las Vegas in the early 1950s and began photographing the town. You can chart the transformation of Las Vegas from a town into a growing city by looking at the photos and negatives that are in this collection. Mitchell's work spans the mid-1950s to the late 1970s and includes aerials.
