Of all the pop brands out there, the one you usually see being used as a store sign somewhere is Coke, followed by Pepsi. Other things show up, but are few and far between compared to the Big Two. This one's a sixties Sprite sign, advertising a grocery store in Rockford, Illinois. I've only ever seen one of these old Sprite signs, up north near Wisconsin, perched on top of an old gas station in the middle of nowhere.
I think it's pretty cool, especially with the stars in the middle section, and it's in fantastic shape.
