This appears to be an early pair of
stereo photos. The figures are different in the two photos, and there
are several shadowy figures in each.
This suggests that a long
time-exposure was used, and that the photos were not taken simultaneously.
Many early photographs required the
camera to be moved between exposures. In later years, cameras were produced
with two lenses to take two photos simultaneously.
