Had to come back and look again.
I don't think I have ever seen a jersey with as many obvious, clear photo matches in one photo either, there must be 15 or so, counting repairs, threads, snags, marks etc. All so obvious too. Amazing.
And Nitschke is arguably one of the top five (two?) best linebackers of all-time, certainly in the 60s he was among the top three and Sport Magazine said he was the best, better than Butkus.
