Vintage postcard celebrating America, the Pilgrims, and Mr. Turkey.
The people who settled in Plymouth, Massachusetts, and celebrated their first harvest in 1621, were feeling lucky to have survived that first year. They invited some of the Indians to join with them in celebration and the Indians all brought their families, as was their custom. The Pilgrims looked around and were a little worried they might not have enough food for the (now) large assembly.
The Indians could see the problem and went out hunting so there would be food for all. Thus began the tradition of sending out someone at the last minute on Thanksgiving Day to pick up more food.
