On the left, an editioned impression of a color woodcut print by Jim Eder.
On the right, an unsigned color trial proof or progress proof of
the same print by Jim Eder.
These two prints allow you to see how the print on the right led
to the artist’s choice of color development to arrive at the
editioned version of the print on the left.
The print on the right also serves to explain another issue:
one reason why a work of art is not signed by the artist.
Eder most likely saw the print on the right as a step toward
the realization of the print on the left, something less than
a finished work of art. He probably had no thought of selling
it, hence the lack of signature.
Two points of information derived upon comparing two
different but similar versions of the same print.
