IIRC, it was long ago asserted, but never proven, that CarlJonesImage was waving, and/or had an arm raised in Altgens6 Photograph. And, I have to conclude there is still no provable evidence for said assertion. The material pattern of the long sleeve shirt as seen being worn on BillyLoveladyImage, matches the arm and torso. It does not match the material pattern of the long sleeve shirt as seen being worn by CarlJonesImage.
It also continues to be my conclusion that BillyLoveladyImage is near, and likely holding onto, the then center placed handrail, as Altgens6 Photograph was made. However, the primary object being photographed, from the front, was the LincolnLimousine carrying PresidentKennedy with wife Jackie, as well as GovernorConnally with wife Nellie, and the SSA driver and SSA co-driver. And, the TSBD entrance portal is in the background some distance back of/from the limousine.
When considering the portal area distance, camera angle, as well as the fact that it is photographic background, I have to conclude the evidentiary value is reduced, and additional image information, and/or testimony is needed for reliable provable corroboration.
