Yes, there are several different types of stereo viewers available for
viewing larger prints. The old style that I think works best was an X Ray
viewer which is no longer made. However, I don't think any of them work
especially well for "artistic" (that is non-technical) purposes, so I
designed and have manufactured one which is available through Steve Berezin
http://www.berezin.com/3d/Hyperview.htm
(or myself but I am running low right now). This viewer is made to view
images approximately 10" wide (20" for the pair). I made the viewer with the
intention of using it for exhibitions and other presentations. I just
returned from the reception for an art exhibition in Yosemite called
Yosemite Renaissance XV in which I have 2 large stereo pairs. The viewers
allowed many of the approximately 200 people at the reception (not everyone
chose to look at them) to view them and there were the usual "oohs" and
"amazing" and that sort of thing, not the mention the occasional "how did
you do that?" The viewer can be used for either prints or transparencies,
but 4x5 would be a little small. While I enjoy transparencies, I am a
dedicated negative shooter and make both stereo cards and large prints (both
b&w and color). I realize that I am in the distinct minority in this group
and have no particular desire to convert anyone, however, if any of the new
members (or anyone else for that matter) needs help in making either cards
or prints I will be happy to answer questions.

Speaking of 4x5 (I guess that was the original topic I am responding to), I
also shoot a lot of 4x5 (mostly b&w) with a pair of homemade cameras (with
new Schneider lenses matched at the factory in Germany). The large negatives
are particularly nice for making large prints with lots of sharp detail.
