Mark Knowles' theories of pharma and other labels

[Stephen Carlson]

Among the historical systems, Fontana and steganography appear to be closer to the VMS (though with considerable differences). 
Both Timm and Schinner's and Rene's systems are good matches for some of the features of the VMS: T&S match more features, but mod2 has the advantage of being a cipher system that can encode any meaningful text.

Thanks for the wonderful chart. That Fontana MS is really impressive as a comparandum. I wonder if something like that was a model for how the VM should look, even though the process used to produce it must be different.
