I bought this postcard on e-bay, thinking it was a photo.  Although it isn't, it shows the Central
Mill in the early days, as well as the (1) S. S. & G. Mill, the (2) Bilharz Bluebird, and the (3)Tom L.
The scale is off, but it gives us an idea.
You just have to love the idea that this is "near Joplin, MO"
