‘The Negro Motorist Green Book’. A guide book that listed all the places that welcomed black travelers in segregated America. Published from 1936 through to 1964

‘The Green Book, which was published from 1936 until the passage of the Civil Rights Act in 1964, listed establishments across the U.S. (and eventually North America) that welcomed blacks during a time when segregation and Jim Crow laws often made travel difficult — and sometimes dangerous.

“Carry The Green Book with you. You may need it,” advises the cover of the 1949 edition. And under that, a quote from Mark Twain, which is heartbreaking in this context: “Travel is fatal to prejudice.”’
