Duh... of course this makes perfect sense....
The picture was taken w/ a table-pod, "handheld" to a railing, and I do
have a 35/shift NOW, not then... ah well...
Thanks!

Ok, so John Lind says it so much more eruditely:
"This image has "keystoning" because the rectilinear lens did exactly what
it was supposed to do. The lens was tilted upward from dead
level. Vertical lines in the street lamp and buildings were no longer
parallel to the film plane. As soon as the camera was tilted upward,
vertical lines were no longer parallel to the film plane. The result is
converging vertical perspective lines. It looks much more natural if they
are horizontal lines; e.g. photographing the corner of a building with
roof lines converging to the ground as they recede toward the
background. Exception: a very radical tilt upward which gives the viewer
an expectation the vertical lines should converge. Avoiding converging
vertical lines is one of the reasons the shift lenses were created.
With a rectilinear lens, the *only* parallel lines in space that will be
parallel on the film plane are the ones parallel to the film plane."
Short of $$$ for a shift lens and time to set up the tripod and adjust the
lens shift - and happening to have all that stuff as you cruise down the
street, the solution is still:
A solution is to keep the camera level and crop out the distracting
street level stuff later. Works for all WAs, of course.

Some reason I like this picture quite a bit:

surprised by the building distortion on the left, as I'm pretty sure I
was using the 50mm lens at that time.
