The Prayer Man photographs show a person with bare arms (i.e. the shirt is either short sleeved or is a long sleeved shirt where the sleeves have been rolled up).
One thing strikes me about the shirt that LHO wore on the morning of the assassination, I cannot see any obvious creases on the sleeves of the shirt to indicate that they had been rolled up.
I would have thought that the shirt sleeves would be creased at various points as the shirt was rolled up from cuff to lower elbow. Is this problematic for the theory that equates LHO with the Prayer Man.
Maybe others can see creases where I cannot or maybe there is a good explanation to explain them away.
