...I should know because I make them! Lithography 
is an age-old art of using chemical processes to 
print art on paper from a smooth stone surface. 
The chemicals etch the design onto the stone 
without giving it any texture - it's an amazing 
process. But I won't get too into it - there are 
too many steps. All you need to know is, what 
you're looking at is not a cel, it is a fine 
print. If you like the image, I'd say it's worth 
getting!
