Could it be that what I have been seeing as Mr. Oswald's raised right arm holding a Coke is in fact Mr. Lewis' raised left arm, and the 'Coke' is part of the flapping object we see in Towner?
Now!
For many, many years folks have asked the question,
'Where the heck is Lovelady's left shoulder in Altgens???'
Well!
The flapping object in Towner, whatever it is, appears to be two-toned---------darker towards the (our) left and lighter towards the (our) right:

Could BOTH areas marked in red here belong to this flapping object, which the person continued to wave at the Parade even after the limousine had passed?

It would certainly explain the missing Lovelady shoulder!
If this is the correct solution, then the 'investigating' authorities panicked when they saw the original Altgens because
they thought it showed Mr. Oswald's Coke bottle................
