We offer a card viewer which can handle larger print sizes than the
little Reel-3D viewer.  It is designed for Holmes cards which are not
quite as big as 2 4 x 6 prints.  I tried to view some 4 x 6 prints with
it today and found depending on how close I was to the image I had to
overlap them from 10-25%.  

These are designed for up to a little over 8" total width and two 4 x 6"
prints would total close to 12".  I found with my eyes I could resolve
up to 10 3/4" width but I would not recommend going above say 10 1/4"
for the general public. With the AO viewer (Reel 3D) I could get to
about 9 1/4" total width, but again it was stretching the useful range
of the viewer.

To be safe I would suggest that you use our viewer for images whose
total width would be less than about 8 1/2".  I think the AO viewer is
recommended for under 6".  

Ours are the same ones that come with a membership to NSA (Stereo
world).  See:
