Yes, I have seen that image before, and possibly, an actual photograph form a similar angle.
I do see a resemblance of LadyImage as seen on the stairs speaking to a gentleman, to ScarfLadyImage and PrayerWomanImage.
My time guesstimation would be as LadyImage is leaving the TSBD Bldg for the day, maybe about 2:20pm CST on 11/22/'63. Certainly no later than about 2;30pm CST.
Good find, good post.
Note the young "reporter", noticed in other images posted in this thread, Murray or Allen and Willis.
Also note the two cops still guarding either side of the door, they weren't there forever. So late in the first hour IMO...
