New York, October 15 : Former US President Bill Clinton had sent a “racially insensitive” postcard to his grandmother Edith Cassidy in 1966, which showed a black youth eagerly polishing a gigantic watermelon.

He was just a 19-year-old sophomore at Georgetown University at that time.

"Dear Mammaw, Thought I would send you one of your cards just to prove I'm using them! My tests are over and I'm just starting the second term. Hope you are well and happy . . . Love, Bill," the New York Post quoted him as writing in the postcard.

Online auction house rrauction.com will sell the card, entitled ‘Hope, Arkansas - Home of the World's Largest Watermelon’, on Wednesday.

The auction house calls it "a throwback to the outrageously broad portrayals of African-Americans of a century earlier."

According to it, Clinton wrote it "in the midst of the most active civil-rights movement in American history," and that he would go on to become "one of the greatest champions of racial minorities among modern American presidents."

Clinton’s representatives were unavailable for comment. (ANI)
