If you are old enough (born before 1995) there is a great chance you will remember the chewing gum inserts, a lot of kids loved it, including myself. I remember buying a lot of Turbo Kent chewing gum and chewing them until my jaws hurt :))
We played a lot of games with the prize being the inserts inside, almost all kids from my neighborhood collected them but with the time we just put the inserts in books or in shoe boxes and forgot about them.
Last week, while doing some cleanup in my old stuff I found 7 Turbo inserts and I decided to make a catalog for them on Allnumis along with another user Radu Florin ( http://www.allnumis.com/user/profile/raducioiu9424 )
If you have such chewing gum inserts please help us revive this cool collectible
