An artist's color rendering of a man riding a wagon cart pulled by two burros. Written on back of postcard: "The burro is a hardy, homely, pathetic, yet ludicrous little chap, an interesting bit in the colorful drama of the west. The burro and pack train are inseparably linked with the West's early history, especially with the prospector and mining." The postcard is titled "Blazing the Trail to Hoover Dam, Near Las Vegas, Nevada."
