Viewing a phantogram is definitely a different experience than viewing a
perpendicular stereo image.  The angled perspective of the phantogram
makes the stereo image appear as part of the actual surroundings.

I have the book from Reel 3-d about constructing phantograms from line
drawings, and the samples that they enclose are simple, but do exhibit
the qualities that make these images unique.

It appears to me that the philosophy in phantograms is to make the image
always "come out of the window", with a special effect being "into the
window".  This is the opposite of a perpendicular stereo pair.  With a
phantogram you are not aware of a window at all, the image appears to be
part of the surroundings.  The window is a floor.

Do I remember a similar effect using perpendicular stereo pairs
exhibited by Robert Thorpe on his web site?  It modified the stereo
window shape to gain a similar effect.  What is the relationship between
this window technique and the phantogram?
