 Was that Mona Lisa in the CHM / VCF exhibit done on a plotter or a printer?
 I have no doubt there were overstrike or printed versions, but I thought
 that one had something different about it. 
    Internet sources state that the "Mona by the Numbers" image was done on
a plotter.  There is some info and a few links at the bottom of this page:
