Unique photos of the 1940s in color codes.

"We imagine photos from those times exclusively in black and white. These are the works of American freelance photographer Robert Yarnall Ritchie from the archives of the Southern Methodist University of Dallas, Texas. Richie was engaged in advertising and industrial photography, working on orders from major publishers and various American companies.

His archive contains a large number of works devoted to the US oil industry and aviation. The last topic interested Richie the most, since he had a pilot's license and loved to fly very much. Some of the photos were taken on color film by Kodachrome. Unfortunately, there are not very many of them, but they are, in my opinion, the most interesting," says blogger samsebeskazal.

Lockheed Model 12 Electra Junior is an eight—seat passenger aircraft (two pilots and six passengers), produced since the late 30s for small airlines.

He was one of the first "business jets" - planes that were bought by private companies to transport their top managers and executives.
