Sometimes I like to try to solve some questions regarding some of the photos. I believe that I have resolved some items in the photo that Lance posted in, I believe, the first post of this thread.

1. First I believe that Royell is correct about the small tree (blue arrow). It appears to have been transplanted from north of the pergola shelter to south of the pergola shelter. The image that James Hackerott posted shows what seems to me to probably be the same tree but apparently north of the pergola shelter. I have viewed the possibilities in a good 3D computer model from various angles, and it appears to me that Royell is correct and I stand corrected for my assumptions in my earlier post. Thanks Royell.
2. However, as I believe Lance already pointed out, there is clearly visible the distinct rear end of a 1965 Chevrolet (yellow arrow). The 1965 models would not have even shown up in the showrooms before the fall of 1964. So that would be the earliest this photo could have been taken, but probably a bit later than that. Therefore I believe that transplanting a small tree like that to a different location (at least about a year after the assassination) should be considered a normal and typical maintenance revision and irrelevant to the assassination. Since it is irrelevant, we have no reason to need to know why someone decided that the small tree should be relocated.
3. The upper part of the post office building can be seen upper left of the image (red arrow).
4. This photo does appear to me to have been taken from the vicinity of the tower. However, it does also appear to have been taken from standing on the ground level versus from the 14’ level of the tower. This was determined by viewing various angles with a good 3D computer model.
