While the cornucopia is probably the most "accurate" symbol for Thanksgiving, it was already kind of an obscure image 40 years ago when I was a kid.
I remember grade school teachers decorating bulletin boards for Thanksgiving. There were turkeys, and pilgrims, and cornucopias (cornucopiae?) and autumn leaves... Even then they had to have a lesson on the cornucopia because we kids didn't know what it was. Flash forward and I doubt the elementary school teachers even bother to teach the kids about the symbolic elements of the season.
The Turkey represents the meal, which embodies the "plenty" which is what *I think* the cornucopia represented.
