The BC/Tom Kuhn YoYo Extreme Team "Fixed Axle Challenge" 8-panel sheet.
Instead of a yo-yo competition against others, the fixed axle challenge had you competing with yourself to attain different colored levels. When you completed one color level, your local retailer or a member of the Extreme Team would affix a large sticker of the same color to your sheet.
The "no brainer" or "anti-brain" design on the front of the pamphlet, and the text on panel 8 were both in reference to Yomega's Brain yo-yo that What's Next was competing against at the time.
