upon information conveyed by exactly repeatable visual or 
     pictorial statements.
          This means that, far from being merely minor works 
     of art, prints are among the most important and powerful 
     tools of modern life and thought. Certainly we cannot 
     hope to realize their actual role unless we get away from 
     the snobbery of modern print collecting notions and 
     definitions and begin to think of them as exactly 
     repeatable pictorial statements or communications, 
     without regard to the accident of rarity or what for the 
     moment we may regard as aesthetic merit. We must look 
     at them from the point of view of general ideas and 
     particular functions, and, especially, we must think about 
     the limitations which their techniques have imposed on 
     them as conveyors of information and on us as receivers 
     of that information.
