This thread is making my brain hurt, but in a good way...
Cameras back then had one focal length. You could switch lenses but it took some time. Also, photographers were right on the field "in play". From the two pictures that are fully visible, you can tell from the Holland Coffee sign that the camera was in two different positions (closer in the top shot) from those two shots so clearly could not have been the same pitch.
Now, to seal the case, you can use a little simple geometry and check the angle of the shadows in each picture.
Just saying how, not going to do it myself.
