Ghost picture-Monks in Hull House

Monks in Hull House
A black and white infrared picture taken at Hull House in downtown Chicago, Illinois by Dale Kaczmarek in November of 1980. This is enlarged blowup of the interior staircase of this most haunted house in Chicago. There was nothing visible to the naked eye when the photograph was taken but what appears are four distinct shadowy monk-like figures standing on the bottom four or five steps. The one directly in the middle appears to be dressed in monk's habit with his two hands together in prayer. There are two other figures to the left of the center monk and one to the right superimposed on the banister which apparently has no head!
