"Girl on the Billboard" is a 1965 single released by American country music singer Del Reeves.
The song is about a truck driver who falls in love with a picture of a beautiful young woman, whose towel-clad likeness is plastered as part of a roadside billboard advertisement along Route 66.
The truck driver drives a daily freight route from Chicago to St. Louis along the highway where the billboard is located.
Early one morning (4:45 AM), while his diesel idles nearby, the trucker knocks on the door of the artist who painted the billboard and (presumably) asks for the model's contact information.
Disillusioned at his fantasy being ruined, the trucker moans that along the highway, "You'll find tiny pieces of my heart scattered every which a way."
