Different upsetter label designs?

[nugs]

I tried to do a couple searches but couldn't find any information... I was wondering if anyone could explain the difference between upsetter label designs?

Can information such as the year or pressing location be determined by the different designs?

Jeremy Collingwood has just released a book called -Kiss Me Neck-A Lee Perry Companion. Just got a copy Friday last and this has all the info & label scans you could want.
Great Book Very informative.
