'This is ridiculous! There's no reason to think that's a flag!'
Really? What do
you say it might be then?
A handkerchief? Nope, too big for a handkerchief-----this is clearly wider than the breadth of the black man in front of Mr. Oswald.
A lady's scarf? Nope, there is no woman there to wave it (Ms. Reese's empty right hand is busy shielding her eyes).
A jacket? Nope, it forms too perfect a rectangle when not flapping furiously.
So................
what then, if not a flag?
'LHO holding up a Cuban flag? That's quite a reach!'Really? Which part is a reach?
The LHO bit? Well, we know Mr. Oswald is right there beside/behind it, and the only other possible person who could be holding it (the black man in front) does not look to be pumping his arm left and right.
The flag bit? See my first point above.
The Cuban bit? Ask yourself: If Mr. Lee Harvey Oswald were to wave any flag at a passing U.S. President, which flag do you think he would wave? Bit of a no brainer, dontcha think?
Friends, I invite you to picture Mr. Oswald, standing in the selfsame spot we have just seen him at in Hughes, holding out his left arm and moving the flag from side to side. The wind, as well as the basic physics of flag-waving, mean that the flag goes back and forth between a state of furious flapping and one of being more smoothly visible. Which is exactly what we see here:

Note the
stable position of Mr. Oswald as he comes in and out of visibility just behind the flag---------in the EXACT same place we have seen him not two seconds ago in Hughes.
Now! I talked about Mr. Oswald holding the flag in his left hand. But how exactly is he holding it up? If he is clutching it at its top right corner (=right-hand side from his perspective), it will just hang down in a collapsed mess.
No, there must be something solid that has been attached to the right-hand side of the flag, and Mr. Oswald must be gripping that something in his left hand. Something like a piece of wood. Something like a metal bar. Something like a-----------------curtain rod.
