A national Thanksgiving Day is observed in the United States as recommended by President George Washington and approved by Congress. On November 26, 1941 U.S. President Franklin D. Roosevelt signed a bill establishing the fourth Thursday in November as Thanksgiving Day in the United States.
The image below, courtesy of Western Waters Digital Library, depicts in “sign language” (or pictographs) how Thanksgiving day is celebrated by the American Indians. Theodore Lambie, young Sioux, created this picture for the readers of “Indians at Work,” official publication of the Indian service, in 1937.
