Cornucopia

The cornucopia (from Latin cornu copiae) or horn of plenty is a symbol of abundance and nourishment, commonly a large horn-shaped container overflowing with produce, flowers, nuts, other edibles, or wealth in some form. Originating in classical antiquity, it has continued as a symbol in Western art, and in North America is particularly associated with the Thanksgiving holiday.
