This is a mid-80's advertising yo-yo made for the Sporting Goods Store, Kreeger & Sons. The store is out of business, so much of the history is unknown. Quantities and the exact date are a mystery, but this a very difficult to find mandala. So I am guessing about 100 from rarity.
This one also brings up a collectors issue. I purchased this one because of the unique wood grain. Some believe it adds to the beauty of the wood like I do. Others feel that a grain discoloration like this make it a reject. No piece of wood is perfect or identical, so I feel it makes it one of a kind and more precious.
