i heard nuggas on my block say its to signify that it's not fake and the gold sticker is usually the " New Era" Logo and size and showing it shows authenticity

As if it were a $3,000 + Rolex
I see a lot of white and hispanic guys wearing 'em with the sticker, even Jay Cutler did in a video?
The thing is , every New Era cap has a small label tab that shows the brand, washing cautions and size INSIDE the cap.
Reminds me of when ol' Minnie Pearl of Grand Old Opery fame wore the price tag hanging off her hat.
It was a joke-goof on the idea that a hillbilly would want to "show off" that is was a "store bought" hat.
Her price tag thing was part of her act and a complete goof.
It amazes me that anyone would feel the need to show obvious visual proof that they had a real hat on. wtf>
That is pretty sad and pathetic when you think about it.
