Sundown Towns After Reconstruction and before the civil rights era, signs like the one in our story popped up on the outskirts of thousands of small towns across the country, warning “colored people” to keep moving. This created a huge problem for the Black traveler and inspired an annual publication guidebook from 1936 to 1966 for African American motorists, called The Negro Motorist Green Book, or just the Green Book, after its editor, Victor Hugo Green. It also inspired the title of the Academy Awards’ 2019 winner for Best Picture.
