Offered is a real nice vintage 7 Up advertising pinback or really, a fold tab button.  It features some real cool funky animation of a dog and a duck dressed up formally and the duck is holding a bottle of 7-Up.  It reads "You're the Un".  This button measures about 2" in diameter.  It is in excellent condition with only super light scratching to it.(I used a loop to see it).  The tab is unfolded.  This button is marked "Green Duck Co., Hernando, Miss., 38632".  A great advertising soda pop pin of 7 Up to add to your collection.
