A library that covered up a drawing of a black female slave having sex with a white man after workers found it inappropriate has put it on display again. 

The drawing, created by black artist Kara Walker, shows the horrors many blacks faced after the Civil War and during reconstruction and includes a depiction of a slave performing oral sex. It also depicts hooded Ku Klux Klan members standing around a burning cross. 

It initially was hung during Thanksgiving in the Newark Public Library's second-floor reference room, but officials reluctantly covered it with a cloth after one day because some workers complained it was insensitive.
