Your photo is very nice.  The plant is NOT
poison ivy.  It is a species of blackberry
(first guess and most-likely in my opinion),
blackraspberry, or a relative.  Without flowers
and fruits it is difficult to be more specific.

The deeply pleated leaves with fine-toothed
margins and the presence of prickles are
the diagnostic features in the photo.

Did you use a digital camera, a video digitizer,
or scan of a photographic print?
