My love for antiquated medical illustrations... expressing itself in book form. This meandering illustration of the nervous system includes all sorts of non-nervous system things. For a good time, grab one of these, find yourself a magnifying glass and a cup of tea and dig in. 
 
These are ~4x6" books with 100lb cover stock and 48 blank pages inside. 
 
Each book comes with a matching matchbox.
 
Enjoy.
