Cheese,
You waffle iron guessers have me convinced. I think you must be right. I assume that this piece was heated and then placed down on the batter which was in another pan? Anyway, it is an interesting piece and since it was found about 9" down in a campsite I am convinced that it was being used in the CW even though I think it dates from before then. I also like your idea that it possibly is European. That would explain the appearance of the horsemen. Gypsyheart has just posted a very viable theory, also. Thanks everybody for all the posts.
