This is a Canada Dry Bottle Cap flying disc. Circa 1970s-80s, produced by Republic Tool and Manufacturing Corp. It is in new condition w/hanging tab intact. Underside of the disc provides instructions for how to make it "FLY, FLOAT, AND SAIL!" with "A QUICK FLIP OF THE WRIST". I don't know about you, but I'm super excited about all that!! In fact, I'm so excited that I'll include a second Canada Dry Bottle Cap, for free. Since it has lost its hanger and has a 1" crack in the center, you can use this second disc to "PLAY CATCH!" "PLAY GAMES!" and "MAKE IT CURVE!" all while keeping your other disc in pristine condition.
