It's pretty simple... while card companies were flooding the hobby with autographed cards, Fleer took things to the next level and started adding one of these cool, fitted, MLB licensed caps into each of their Legacy boxes.
I know they're not for everyone. They take up a lot more room than a 2.5" x 3.5" piece of cardboard and are much more difficult to display.
But like humans... if you love something enough, you're willing to accept them for whatever they are.
Happy Friday and sayonara!
