From the Internet:
"OFFENSIVE SNACKS OF YORE


















Sambo's restaurant was weird all around, however. As you can see from the picture above, there was nothing more than some happy Indian lad eating pancakes with a tiger by his side. But Sambo's roots in the story "Little Black Sambo" made it too sensitive of a character to last. The book, which featured a nappy haired black boy with stereotyped features, and parents named Black Mumbo and Black Jumbo, was offensive enough to eventually spell doom for the restaurant chain. Of course, blacks have been no strangers from offensive foods, with grinning characters from Cream of Wheat, Uncle Ben, and Aunt Jemima still happily serving white folks breakfast to this day."
