I certainly don't have the experience to cast judgment here, so I've just been watching from a far.
But if I were to give my opinion, it's hard to argue with Kevin's evidence/logic of the logo change in 1957, and this sign is of course dated 1959.

If I did play in this high end game I may have gotten bit. Because I would have sworn I learned on Oldgas.com, that if the sailboat mast points at the "I", then the sign is good.

One thing of note is the thickness of the black circles around the stars in the upper left & right. In fact, it seems all of the black is more prominent on Wes's, and I'm assuming Kevin's sign.
