Just to build on Simon's post about these jerseys, Ripon released a number of these jerseys (I think 2009-10, given the Jets / Titans AFL throwback with the 50th patch was featured). I'm not 100% clear on whether they were released as blanks and customized after the fact, or whether Ripon made them with names / numbers. I'm inclined to think the former.
These jerseys were never intended to be worn in games, or issued to teams (the fact that the players and sizes do not match-up is kind of a giveaway...) Having said that, they are amongst the best quality of jerseys I own. I have a Peterson Vikes T/B, and Alstott and Sapp creamsicle Bucs' T/Bs.
I have only ever seen the throwbacks. I've seen a Pats (Brady), Lions (can't remember player) and Titans (again, I forget the player).
The final thing to add is that they run a lot smaller than the label size indicates. I have two "XX-Large", and they run somewhere between a Reebok 50-52. The final one I have is an "X-Large", and it's more like a 48-50.
Hope this helps,
