Inspirations: Vintage Books no.2

I found this 1950 Random House book about The Pony Express in a used book store in Rochester. The design of it just really caught my eye, with the relatively simply graphic design cover and the inside illustrations. With the exception of the inside double page spread on the cover, the only other illustrations are spot illustrations at the beginning of each chapter. However, I find the simple color scheme of black, white, and the faded yellow as the midtone, to be very appealing. I would like to experiment more with this super simplified approach to color.
