I found one today in my front yard in Southeast Missouri. Hard to find. Thanks so much.

Cool find … Jay told me what these were when I found one at Ha Ha Tonka.
I also did not find any color illustrations when I did a search, although I
did track down a small B&W engraving from an old article. Glad you got these
