Day Glo Orange marking from the Cold War

 

Always like the Day Glo marking marking

C-54 from the 50's and 60's

 I would call the 50's and 6'd the heydays of the USAF.  The aircraft had colorful markings.  THe C-54 cruised the world delivering cargo all over the world.   To the arctic, Greenland, Europe, South American, Anti Arctic and all over Asia.
