See that "retired" Gerald Ford #48 jersey? MAKE SOME COMMEMORATIVE JERSEYS LIKE THAT.
The old, non-nylon, non-fitted style, that you could actually, like, wear for fun without shoulder pads. The small-sized stitched tackle twill numbers. Make a number 48, a number 11, and a number 98. And as many others as people want. You'll sell quite a lot of them, I think. You could pretty easily sell me a #98.
