I saw Hidden Figures last weekend and liked it. I was appalled by the Jim Crow law signage portrayed in the film.
On thing occurred to me - I had never seen a "White Only" or "Colored Only" sign on a bathroom, drinking fountain, etc. I was born in the early 1950s and never traveled to the south before the late 1960s when I was a teenager. We flew to Florida, so no travel through small towns. Were those types of signs gone by then?
