I would like very much to have one of the Lions' 50 Seasons jersey patches from 1983.
The Lions reused their game jerseys for practice drills for many years. For example, I've seen photos of home jerseys with the sparkly silver numbers (last worn in 1981) worn in the 1985 training camp.
I expect the patches were removed and the 1983 jerseys were reused. Any leads will be very much appreciated, for either a loose patch or sewn on a jersey.
