All signs lead to....

[G.Pope]

I am having a hard time dating this sign, I have had it for years and have not seen another one like it to date it. I know that Stout produced these signs into the 50's, but this one is different from the rest. Note the art deco "fresh up". it has no sign number or date code. It also has Reg. U.S. pat. off. It also says Stout Sign co. St. Louis, MO. Made in USA. It is about 40" tall. Most of these signs are two-toned, and just asking if anyone knows for sure.
Thanks guys

On page 119 of Petretti's 3rd Soda Pop Collectibles Price Guide, there is a smaller octagonal sign that has the same font as your

He dates that one to the 1940's
