I know, I checked. :thup:
In absence of the piece I know
was part of the 30year anniversary label, I've just looked at the labels on bits do I have which are quite recent - they have the "the original" written at the bottom too.
Some are dated 2009, some 2006.
I think this label is simply the most recent. I'm fairly sure the 30 year anniversary one is rectangular and has "30 years of excellence" written on it. Suzy can confirm!
