I have to agree Walt, I can't make any sense of the boxes as they are positioned in the museum.
Where was the rifle hidden?
I believe that the dark area at the extreme right of the photo is the stairway wall going down to the fifth floor....
There is a dark haired woman who is wearing a COVID mask facing east at the left side ( east side) of the photo ....
I wonder why they didn't place the boxes as they were when Weitzman and Boone found the rifle
?
