In 1953, a grocery advertisement in a Jackson, Tennessee, newspaper advertised Nigger Head Oysters for 45 cents a can.[1] There was nothing unique or even rare about the advertisement; Nigger Head Oysters were sold in many of the nation’s stores, particularly in the South. The product’s name offended many Americans, especially those in the young civil rights movement. In August 1955, Jet magazine reported that the Aughinbaugh Canning Company of Biloxi, Mississippi, had changed the name of its brand from Nigger Head Oysters to Negro Head Oysters. The change resulted, in large part, from pressure brought by the NAACP.
