I have seen a few illustrations of antique Rough Rider chips. They appear to be a little different than any I have actually seen. I wonder if they were just rough art to show a style but, not actually true art of the real chips. Here are the five varieties I'm aware of and two illustrations from old catalogs I have not seen as real chips. I reversed the darks and lights on the blue chip so you can see the design like the others. Comparing apples to apples.
